16:39:06| Failed to update Gitlab commit status for project '9': RESTEASY004655: Unable to invoke request

Problem description

We already have Jenkins/Gitlab integrated in our production environment using the gitlab-plugin, but we need to update our environment (Jenkins: 1.1609 / Gitlab 8.8.3 / Plugin: 1.2.4)
We updated our dockers image in an dev environment to test it out, but we were unable to update the plugin, since the latest version can't connect to Gitlab.

I tried to reinstall the plugin and setup it again. But the same error ocurred.

I also tried to curl gitlab API and it was succesfull.

Can you try unchecking 'Ignore SSL Certificate Errors,' given that you are not using an HTTPS URL to access GitLab?

Sorry for taking a long time.

Same problem, and if I upload the gitlab and jenkins version but keep the gitlab plugin at 1.2.4 the connection is successful.

I was able to get this other stack trace

Hi, do you need any further information? I'm still getting Connection timed out with the plugin 1.3+

I'm using the 1.2.4 for now, but I would like to upgrade to a newer version

I did more testing, and starting from 1.3.1 I get the connection timed out problem.

I was able to identify the problem and replicate the error

Since we are behind a proxy we set the HTTP Proxy Configuration to another IP/Port If these proxy are unavailabe it hangs until we get a time out connection.

To replicate this just set those configuration to an invalid IP and Port

@DiogoLG in 1.3.1 we added support for HTTP proxying: https://github.com/jenkinsci/gitlab-plugin/issues/382

That would explain why this breaks for you starting in 1.3.1. So it sounds like this is not a plugin bug/issue? If so, please close this. Thanks!

Ok, that makes sense.. Since the error happened just because our proxy configuration was wrong, I agree on closing the issue, although a better solution would be to consider the no proxy configuration on Jenkins.

jenkinsci / gitlab-plugin
