I am trying to setup my first ec-2 instance in AWS and keep geting "ssh: connect to host ec2-xx-xx-xx-xxx.compute-1.amazonaws.com port 22: Connection timed out"
I followed all the solutions but nothing seems to be working for me.
Here is my inboud rules defined in security group:
I added ICMP rule to atleast ping my ec2-instance but noting seems to be working.
Steps I have tried so far:
Instead of "Anywhere" I added my ip to allow inbound connection,
opened port 22 through firewall.
Enabled ICMP from firewall.
Disabled Firewall.
So far nothing worked. Please help as this is my first exp with AWS and already have spend hours trying to figure it out.
Update: Added ACL rule
I deleted and recreated a new instance and not it works intermittently.

I am trying to connect to AWS RDS database using pgAdmin4, I encounter and error:
Unable to connect to server:
could not connect to server: Connection timed out (0x0000274C/10060)
Is the server running on host "database-1.xxxx.eu-west-2.rds.amazonaws.com" (xx.xxx.xxx.xx) and accepting TCP/IP connections on port 5432?
I have tried to Allow Public Accessibility and InBound Rules from my IP. But I am still getting the error? What seems to be the issue?
I was facing the same error but for the MySQL database in rds. What I did was, I
went to http://checkip.amazonaws.com/ and checked the IP shown. I copied that IP and created a new security group by adding two rules, one is your standard all traffic rule, and the second is the one with custom IP which you just copied. Then went to rds and changed VPC security grp to both default and the one I just created. Do this and try to connect again. It worked for me
For a quick test, try opening your inbound rule like this. If it works, then you know the issue is your IP address in your inbound rule:
Once you set this- can you connect?
Im getting Timeout error on ssh connection to EC2 even after set port 22 to anywhere, i see my user and is ec2-user indeed but im getting timeout everytime
Im already tried reboot the instance and change to other security group, even try Termius software (im on MAC) instead command line but notheing...
First of all, check you VPC and subnets inside this VPC in which you have created your instance. The subnet will have a route table, verify that subnet is attached to an Internet Gateway with Destination 0.0.0.0/0, otherwise add one by referring this link. Post this step, check that your security group has an Ingress Rule for port 22 from your ip(select my ip from drop down). You will not get Connection timeout error if these two steps are configured properly.
I created Ubuntu instance in EC2. And worked fine so far.
But somehow I can't connect to the server by PuTTy anymore and I get Network error: Connection timed out.
The instance is running in the console.
CPU uses just 2%.
InBound Setting seems no problem. SSH with 22 port.
Tried with the IP address and DNS.
restarted the instance and Tried.
Stopped and tried with different IP address.
Instance connection is fine.
This is the screenshot:
This is inbound rule:
How can I solve this problem?
A Connection timeout is a sign that your computer is unable reach the remote computer. Such an error normally takes some time before it fails.
If, instead, the remote computer rejected the connection, the error would appear immediately and the message would be Permission denied.
Things to check:
The Security Group on the EC2 instance needs to allow inbound SSH (port 22) access either from the whole internet (0.0.0.0/0) or, preferably, from a smaller CIDR range that includes your computer (eg choosing "My IP" in the console). This is typically the cause of the issue 80% of the time.
The instance needs to be in a Public Subnet, which means the subnet is connected to an Internet Gateway.
Your network must allow an outbound SSH connection to AWS. Some corporate networks might block this.
There are some other potential causes, but most of the time the cause is one of the above.

I have followed the guide, disabled my firewall, verified my security group allows access to everything (initially set to public). Still, 2 installs of mysql won't let ssms connect. No idea why this doesn't work

could not connect to server: Connection timed out (0x0000274C/10060) Is the server running on host "posttest.cnmcgcqc8rkx.us-east-1.rds.amazonaws.com" (52.2.0.231) and accepting TCP/IP connections on port 5432?
mysql can connect, might have to go with that
ecurity groups are not under RDS, they are under EC2's console. ACL's options are under VPC's console. This is not even mentioned in the guide. Seen someone connect on youtube with my exact settings...
This could be one of many things with the given information. The first thing I would check if you know your security groups are set up correctly is to open the port on the Network ACL Inbound Rules.
I have set up a a micro EC2 instance on AWS. Currently, I am using the free tier in Oregon. There are two problems which I am facing.
When I try to SSH the instance using the public DNS, it says host does not exist but when I try conencting it using the public IP, it connects to it. What setting is needed to use the public DNS ?
I have opened the SSH client using the IP address. I want to set up my application which needs Node.js and MongoDB. I installed Node.js using this
Next I installed MongoDB using this
Then I connected to my instance using Filezilla and uploaded my code to it. I then start my node application which uses socket.io.
When I try to connect to socket.io server using web browser, I get a message which says connection refused "error 111". I have opened TCP port 80 in instance's security groups. In iptables, I have forwarded port 80 to 8080, but still it does not work. I have also checked that the firewall is disabled in ec2. Kindly help me to resolve this issue.
Did you check if all of the necessary ports are open on Amazon Security Policy?
What you can do is to allow all traffic on Amazon Security Policy for test and see if the connection goes well or not.
You might also check if you need access DB from outside. In that case, you also have to open the mongodb port and setup mongodb correctly as well.
Other tools that might useful to test firewall and connection issue will be tcpdump and syslog file
For the dns issue, did you try to nslookup on that name and see if the IP shown matches your server IP?
As Amazon gives a long DNS hostname for the server, I always use my own domain name. It's much easier.
example : ec2.domainname.com, which points to the Amazon IP address
Hope that help.
My problem is resolved now..
For the DNS issue, earlier I needed proxy to access internet, so I guess the DNS name was not getting resolved. When I tried using proxy free internet, I was able to ssh using public DNS.
And regarding connection to socket.io, I used port 8080 instead of 80 and used "sudo node main.js" to run my node file. Now I am able to connect to the socket.io server and MongoDB.
Another thing which I want to ask is that would running the node file with sudo rights create some security issue ?
Thanks for the answer! That also worked for me. I had the same problem trying to connect through sockets (http://myipaddress:3000) to a node.js server, i tried opening ports on the actual ec2 instance and disabling the firewall through SSH but nothing worked. Had to go to Security Groups on the ec2 console and open a new inbound tcp rule enabling that port
