Publish data from MQTT.fx to Cloud IoT Core - google-cloud-platform

Using CloudIotCore documentation I am able to run Quickstart example and EndtoEnd example in my Google cloud platform project.
Using MQTT.fx tool i am unable to connect to same Google cloud Project

A few notes:
Your password will expire after 3600 seconds
I had to enable TLS 1.3 from the dialog before connecting using MQTT.fx
After you connect, you will only be able to publish to device-specific topics and only will be able subscribe to device-specific configuration changes.
There are Java samples out there if you need to use Java, it seems a bit suboptimal to use a client when you'll need to regenerate the password every hour.

Agent Unreachable after restore VMware Horizon Connection Server

After a power outage I got both of my View Connection Servers unbootable with BSOD and I could not recovery it and also I don't have backup of it.
After all steps below I could not get things fixed, all VMs are "Agent Unreachable"
Created a new VM for connection server (WITH THE SAME NAME AS THE OLD "VIEWCS01")
Before doing it correctly I connected the base disk, and not the last
snapshot, to the new VM and broke up the whole thing with the error
"file system specific implementation of ioctl [file] failed", I solved
this correcting the CID - https://kb.vmware.com/s/article/1007969
Installed Windows (Same version)
As in https://kb.vmware.com/s/article/76770:
Installed Connection Server (Same Version)
Restored LDF backup
Removed all View Connection Servers and all Security Servers (vdmadmin -S -s -r viewcs01, viewss01 and viewcs02)
Uninstalled the connection server
Reinstalled the connection server reusing the AD LDS
I did removed the "viewcs01" because with my previous tests I was not removing it, I think because of >this, after the recovery steps done no console was opening, In previous tests I also not using the old >machine name, instead of it I was using "viewcs03".
Ok, Console opened, I changed the vCenter credentials (Just putting password was not working with error - https://kb.vmware.com/s/article/60152 - Log below:

Update to question:
Some piece (That I don't have now) of the log lead me to This KB, so I have uninstalled the Connection Server, remove all certificates and reinstalled it again, nothing changed.
After reading the following links [1], [2], [3]:
I've changed the security mode to Mixed, nothing changed.
But after change it to mixed and after reinstalling the Agent (I've reinstalled it before change to mixed and it didn't worked) from the VM have turned it to Available, I still not able to access machine with tunnel errors (Changed tunnel configurations also).
Updated the Connection Server to 7.13, stopped to open console.
Started the whole process from zero, now machine name is viewcs04, not worked also.
For any who encounter the same problem, I decided to create a new Connection Server and I will create manual pools, so people can work and I will migrate everyone to new linked-clone pools.
Just to mention, I cannot just create new pools, all pools are dedicated and have manually installed applications, printers etc.

Starting service Service Bus Message Broker failed: Time out has expired and the operation has not been completed

when I ran the workflow manager getting the error message at add host to service bus farm.
We have the SharePoint as standalone, OS is Windows server 2012 r2

Followed below two url's for installing

please let me know how to resolve this issue for installing the workflowmanager.
what worked for me was enabling TLS 1.0 in the registry.
in my case I don't have registry of client but only enabled the server one
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Client]
"Enabled"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.0\Server]
"Enabled"=dword:00000001
fyi... I was stopped the Service Bus Message Broker while the workflow manager configuration wizard was running in the "add host to service bus fam" task, then the changes the wizard complete successfully. I hope so much you can resolve this issue :)
this is the link where I fund the answers http://answersweb.azurewebsites.net/MVC/Post/Thread/e6667e72-36db-44d7-bcb9-0d537cd19542?category=workflow and is the CRBenson post, thank you very much
I had almost same issue. Installing the correct patch fixed the issue.

How to deploy Kafka on Google cloud

I deployed Kafka on Google cloud, I changed listeners to
PLAINTEXT://[internal ip address]:9092
And when I try
sudo ./bin/kafka-topics.sh --list --zookeeper [external IP address]:2181
I can get the topic on the broker. However when I try to produce message to the Kafka broker
sudo ./bin/kafka-console-producer.sh --broker-list [external IP address]:9092
--topic test
following error shows up:
ERROR Error when sending message to topic test with key: null, value:
5 bytes with error:
(org.apache.kafka.clients.producer.internals.ErrorLoggingCallback)
org.apache.kafka.common.errors.TimeoutException: Expiring 1 record(s)
for test-0: 1506 ms has passed since batch creation plus linger time
I wonder what properties did I set wrong and how to fix it?
You need to set advertised.listeners to the external IP so that clients can correctly connect to it. Otherwise they'll try to connect to the internal IP (since advertised.listeners will default to listeners unless explicitly set)

Suggests that the CA didn't find the certificate that you gave it (from the admin).
If you are enrolling the admin with the CA to get fresh certificates this should solve your issue.
It seems that you may be using old certificates stored in your KVS store file that pertains to the prior network. This problem is simply caused by you restarting a fresh network and keeping the prior KVS, thus when you run your code, it checks if the user is stored and uses those credentials instead of getting new ones. Always remember to delete your kvs when restarting your network.

Presto server on AWS - Cannot connect to discovery server

Trying to run Presto coordinator server with discovery server embedded on AWS CDH4 cluster
config.properties:

Tried to also run standalone Discovery server, same effect. Looks that listener is started after registration attempt is made.
I was wondering if someone would notice this in the logs :) It's actually not a problem. The error appears because the discovery client starts before the discovery server is ready. You'll see "succeeded for refresh" shortly after in the logs which shows that it's working. We will fix the log message eventually but it's purely a cosmetic issue.
