SMTP Connection Timeout?

[David Cheong]

I'm setting up the Jira Software using the docker and everything work just fine until I try to configure the SMTP mail server. I check on my configuration detail is correct but still having the error of 

Unfortunately no connection was possible. Review the errors below and rectify:

• SocketTimeoutException: Read timed out

I would suggest - build another container with SMTP Server, connect jira container and smtp container under a network.

use the same mail configuration and check if smtp and jira containers talk to each other.

I using the docker images which i found at https://hub.docker.com/r/cptactionhank/atlassian-jira/

When I try to access into the docker, it's only using the deamon user, where I can't telnet or do any root access task. Is that something miss configuration on the docker image it self?

@David Cheong

Your docker container network and your mail server network - they should be able to able to reach each other.

Here it looks like a network issue - your container network and mail server network have restrictions and cannot communicate , check that.

Jira can'T communicate with the SMTP mail server.

I check on my configuration detail is correct.... i dont think so :)

Check theconfiguration again, consider proxies/basic networking stuff/etc.

Dear @David Cheong,

have tried to manually connect to the mail server from the Jira software server? Is it at all available?

Again, log on the Jira server and try a

telnet <mailserver> <port>

I it reachable? Also a timeout?

So long

Dear @David Cheong,

if you want to find the reason, you have to login via SSH on your Jira server. There you can do the telnet. Eventually, the route is blocked from this host. But you have to check it out, before you you continue.

I not able to install the telnet command in the Docker container

Dear @David Cheong,

you need to find a way to get on this machine for troubleshooting. Otherwise it will get really hard to help you.

Can you post the exception found in the log file?

So long

Yup - Jira cannot reach the server. The name will get resolved, but the response of the mail server is not received within the timeout.

Seems, that you looged in on the server. Can you telnet <mail_server> <port>?
