I have two windows computers, both using the Microsoft Edge browser. When I'm typing on the Overleaf website, the connection gets lost every 2-5 minutes. What's worse, some unsynced sentences are gone when the connection resumes. I'm not sure whether this is a network problem since all other websites look good, including Twitter and Gmail. I wondered if this is about the framework of what Overleaf cloud service used. Could anyone give some tips about the issue here?

We're a small 4-man team working on an indie games marketplace.
Like several previous posters before us, we are having trouble with the Windows Defender Smartscreen blocking our app. The most common message is "File is not commonly downloaded" but sometimes it also reads something like "Windows Protected your PC."
We've received a number of complaints from our users about the Smartscreen warning message, and it's badly hurting our efforts with user acquisition.
In accordance with previous threads we found on this topic, we have tried
Code Signing - we sign our code through DigitCert, and have done so for nearly 5 months; the message has not gone away. As we use AWS for our servers, we don't have any way to use an EV Code Signing hardware token.
Microsoft Code Review - We submitted our files to Microsoft for Malware analysis. The analysis came back clean, even with a note saying they could not reproduce the warning, and yet, both our own testing and our users confirms the Windows Defender message is still happening.
Becoming a Microsoft Partner - Unfortunately, even after getting approval and confirmation, absolutely nothing has changed.
Everything I can find online about getting our app whitelisted is about whitelisting specific programs from the user side -- not very useful for convincing people we're safe to download. There are two threads on Stack Overflow that link to a blog article which has since been removed. Microsoft, Amazon, and DigitCert support have all been less than helpful.
My questions are:
1. Is Amazon CloudHSM a substitute for EV Code Signing? As stated above, we can't use a hardware token, but I have to imagine that AWS has some kind of substitute. We've never re-issued the serial on our current code signing cert, but I can't imagine 5 months is a normal turn-around time.
2. Does hosting the download link on our own domain make a huge difference? Currently, the download link leads to an AWS bucket. One website said that could potentially slow things?
3. What else are we supposed to do? We're not a large team and we're kind of stretched thin as it is. If anybody has any suggestions we haven't tried yet, I'm all ears.
I had installed ColdFusion 2018 recently and with the installation less than a month old (and my understanding of the technology even less), my Cold Fusion service has stopped working. I have tried a number of things and have referred to a number of articles and out of many such errors where the service is not being accessible, some of them were able to get it resolved. However, some other obscure reason that may be causing this error have been untouched and unknown.
Whenever, I try to restart the service, I get an error as shown below:
Windows could not start the ColdFusion 8 Application Server on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, contact the service vendor, and refer to server-specific code error 2.”
Without much understanding, I started to google it out. Looking into every one of these posts, I tried
Configure JRE and try to relaunch the service by looking at "JAVA_HOME" variable and JVM.config
Run the batch files in every possible combination to find if anything clicks
Check if the present JAVA version works and is compatible with Coldfusion version installed
Fiddling with the "SessionStorage" var in neo-runtime.xml file as some suggested
and few other tricks coupled with a numerous service restart attempts and a few machine reboots as well.
A service that renders Cold Fusion pages should be shut down abruptly. To add to agony, the CF Admin also depends on the service and hence does not work.
Any pointers to any potential solutions?
At 9am this morning I found that my server was unresponsive I was unable to connection into via either ssh or http/s.
When I finally logged in, everything was fine other then a high cpu (averaging 70-80%). Via the console I see that the disk IO was high and also there was a peak in the amount of API requests per second.
Can anyone point me in the right direction so I can find out what happened ?
Thanks,
What you experienced was most likely the result of the networking issue described here. Also, in general, this forum is a good source to stay updated.
Beyond this, if the time window does not line up with your observations (there's no time zone specified in the question), one would need logs (i.e. Apache's, syslog, etc) in order to determine a possible cause, albeit it can turn into an exercise in speculation after the fact.
Is it possible that a database (connected to ColdFusion 9 via a datasource connection) being unavailable could cause ColdFusion to become unresponsive? (The database is used for a singular one-off lightly-trafficked app.)
Recently, maintenance on a connected Oracle database (oracle jdbc) has caused that database to be unavailable two different times. Coincidentally, at both these times, ColdFusion pages on our site became unavailable or terribly slow to load (static HTML pages seemed to load fine, for the most part). Restarting the ColdFusion application server service would fix the problem, but only for minutes. The first time, during a time the application server was responsive, we unchecked the "Maintain connections" checkbox. I'm not sure this had any effect, then shortly after the Oracle database came back online, and we didn't seem to have the problem any more.
The second time that database was offline, we experienced a very similar issue with our website - ColdFusion pages becoming reaaaally slow or unavailable altogether. During one of the times when I could access the CF administrator, I updated the datasource and checked "Disable connections". Then I stopped and restarted both the CF ODBC agent and ODBC server services. After that, the problem seemed to stop, but I don't know enough to know if this is causation or coincidence.
Anyone have insights on this?
Server setup: Windows Server 2003 SP2, ColdFusion 9, IIS 6
There are a number of ways to slow a database to a crawl if not stop it completely. If you have hackers for example attacking your database through Port 1433 with attempted logins several times a second that can slow it down and if they get in they can of course do whatever they want. When this happened to me I found a record of attacks in the Event logs; the solution is better network security intercepting such attacks and never letting them actually talk to the database. Or say if your site is vulnerable to SQL injection attacks hackers could be messing with your database that way too but network security wouldn't necessarily work in that case. It doesn't require hackers to degrade the performance of your database however, you could be having a problem with allocated disk space for transaction logs or indexes filling up, or heaven forbid an imminent hardware failure showing early symptoms. You're backing up your database often I hope, off the server. To answer your question yes ColdFusion can and will become unresponsive when pages are called that call the database, and will usually display error messages when the database finally times out and never sends the requested data to ColdFusion. You can protect against that to some extent with CFTRY tags around your queries that display clean and polite error messages instead of ColdFusion's ugly ones if the database fails to return data, at least your site continues to look professional that way. One project I worked used a shared SQL Server database that often got overloaded and slowed down terribly and there was nothing I could do about improving that situation. What I did to keep the site functioning was to maintain a DB backup in the form of a MS Access database (yeah it was inappropriate but it worked when SQL Server wouldn't) and anytime SQL Server failed I had the application set up to automatically use code that called the Access database instead.
These are some ideas for you to think about if you are continuing to have problems, I see nobody's even tried to answer your question in the last six months and that's kinda been my experience with the quality of assistance this site has offered me too. I hope my thoughts can be of some use to you.
I have a winsock IOCP server written in c++ using TCP IP connections. I have tested this server locally, using the loopback address with a client simulator. I have been able to get upwards of 60,000 clients no sweat. The issue I am having, is when I run the server at my house and the client simulator at a friends house. Everything works fine up until we hit around 3700 connections, after that every call to connect() fails from the client side with a return of 10060 (this is the winsock timed out error). Last night this number was 3700, but it has been around 300 before, and we also saw it near 1000. But whatever the number is, every time we try to simulate it, it will fail right around that number (within 10 or so).
Both computers are using Windows 7 Ultimate. We have also both modified the TCPIP registry setting MaxTcpConnections to around 16 million. We also changed the MaxUserPort setting from its 5000 default to 65k. No useful information is showing up in the event viewer. We also both watched our resource monitor, and we havent even gotten to 1% network utilization, the CPU is also close to 0% usage as well.
We just got off the phone with our ISP, and they are saying that they are not limiting us in any way but the guy was kinda unsure and ended up hanging up on us anyway after a 30 minute hold time...
We are trying everything to figure this issue out, but cannot come up with the solution. I would be very greatful if someone out there could give us a hand with this issue.
P.S. Both computers are on Verizon FIOS with the same verizon router. Another thing to note, the server is using WSAAccept and NOT AcceptEx. The client simulator is attempting to connect over many seconds though, so I am pretty sure the connects are not getting backlogged. We have tried to change the speed at which the client simulator connects, and no matter what speed it is set to it fails right around the same number each time.
UPDATE
We simulated 2 separate clients (on 2 separate machines) on network A. The server was running on network B. Each client was only able to connect half (about 1600) connections to the server. We were initially using a port below 1,000, this has been changed to above 50,000. The router log on both machines showed nothing. We are both using the Actiontec MI424WR verizon FIOS router. This leads me to believe the problem is not with the client code. The server throws no errors and has no unexpected behavior. Could this be an ISP/Router issue?
UPDATE
The solution has been found. The verizon router we were using (MI424WR revision C) is unable to handle any more than 3700 connections, we tested this with a separate set of networks. Thanks for the help guys!
Thanks

I would have guessed that this was a MaxUserPort issue, but you say you've changed that. Did you reboot after changing it?
Run the test on the exact same computers on your local network (this will take the computers out of the equation).
The issue could be one of your routers not being up to the job?
