io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection Time out: No further Information: - io

I am getting the error message: io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection Time out: No further Information:
Please, can someone help me to fix it? This error message is on Minecraft and it has something to do with the Netty Project! I have been having this problem for about 3 months now!

This means the connection could not be established in the configured connect timeout (the default in netty is 10 seconds). So I would check your firewall.

javax.net.ssl.SSLException: Connection reset exception when connecting DocuSign development endpoint

javax.net.ssl.SSLException: Connection reset
I'm trying to connect Docusign's development endpoint (account-d.docusign.com) through my application. We are experiencing "javax.net.ssl.SSLException: Connection reset" when the application tries to retrieve a JWT user token using "requestJWTUserToken" method. What might be causing the SSL exception? Thanks for any help!
It seems that the connection has been closed by the server end of the connection. This could be an issue with the request you are sending
To aid debugging you could look at using a tool such as Wireshark to view the actual network packets.
The cause could be that the connection inside HttpClient is stale. Check stale connection for SSL does not fix this error. Solution: dump your client and recreate.

504 error on nodejs sails API server randomly across all endpoints

we have sails js as an API server and intermittently we are facing 504 upstream timed out the issue, the call was going till Nginx from there its throwing upstream timeout, there is no log coming on the application server, and it is happening across all the APIs intermittently not all the time, and the traffic on server is very low i.e. 5-10 requests per minute and there is no heavy computation going on, so not sure how can I debug this issue. this is a very random issue. also, there are No server restarts or any other errors on application logs. it's running fine on PM2. we are using an AWS EC2 instance. current timeout is 60 seconds but none of our APIs takes more than 500 milliseconds. we are using the node 6.6 version as it is a legacy monolith app so can not upgrade it due to multiple dependencies and no single owner. and requests are passing through the load balancer to NGINX but some time does not reach the application server. also, the instance size is quite bigger in terms of CPU and memory and traffic is extremely low. this is a very random behavior not specific to API. sometimes it can happen 1 out of 10 sometimes 2 out of 5 requests can through a gateway timeout issue.
some of the logs from Nginx are below-
[error] 31688#31688: *38998779 connect() failed (110: Connection timed out) while connecting to upstream, client 10.X.X.X
2022/04/22 16:36:37 [error] 31690#31690: *38998991 connect() failed (110: Connection timed out) while connecting to upstream, client: <server_ip>, server: <DNS_URL>
guys I have tried almost all the things from StackOverflow but nothing helping me, so please help me to find the root cause so I can mitigate the issue

Apache Pulsar connection refused

In my Pulsar consumer/producer, when trying to connect to Pulsar, I'm getting this error message:
java.util.concurrent.CompletionException:
org.apache.pulsar.client.api.PulsarClientException:
java.util.concurrent.CompletionException:
org.apache.pulsar.shade.io.netty.channel.AbstractChannel$AnnotatedConnectException:
syscall:getsockopt(..) failed: Connection refused:
pulsar-ms-tls.mydomain.com/10.16.60.179:6652
What could be the issue?
You are trying to reach the wrong port. Pulsar, by default, uses port 6651. Please verify that you're using the correct port (based on how your Pulsar cluster has been configured).
It's also possible that your IP address is incorrect, so be sure to double-check that you're hitting an IP address that's running a broker instance.

We have disabled the firewall and it still doesn't work, any suggestions on troubleshooting ?
If this is related to firewall setting that you may want to try to set the connectivity mode to Http. More details at
http://msdn.microsoft.com/en-us/library/windowsazure/microsoft.servicebus.connectivitysettings.mode.aspx
and:
http://msdn.microsoft.com/en-us/library/windowsazure/microsoft.servicebus.connectivitymode.aspx
Try to increase the timeouts on your bindings to 1 minute and add your server application as an exception in Windows Firewall manually.
So this ended up being a simple issue of ou network firewall being restricted. We had told our SA's to open the ports up for 9354 goinging to the sb. They said they did open them... but they didn't. I walked throght it with them and we discovered it wasn't open

Timeout in Email Task in CruiseControl.Net

I'm trying to add a Email Publisher Task in Cruise Control but I'm getting the error below.
Publisher threw exception: ThoughtWorks.CruiseControl.Core.CruiseControlException: EmailPublisher exception: System.Net.Mail.SmtpException: The operation has timed out.
I am able to ping the smtp server from the ccnet server from a cmd prompt.
Failed
Fixed
What could be the cause?
Thanks
Have you tried changing the mail port? I had this same issue the other day, and changed mine to use SSL and port 587, and the issue went away.
Try a telnet to the server + port and see if it is open.
