Webhook execution failed: execution expired

Question

I am trying to trigger jenkins build whenever there is a push to GitLab.
I am referring to https://github.com/jenkinsci/gitlab-plugin.

When I test the connection for webhook it shows execution expired.

I am using:

• Jenkins ver. 2.60.1
• GitLab version 9.4.0-rc2-ee
• Git lab plugin 1.4.6

Answer 1

The exact error message, clicking "Test setting" from GitLab:

We tried to send a request to the provided URL but an error occurred: execution expired

As mentioned in issue 128:

This looks and sounds like a configuration or network error.
Maybe your machine is not publicly available on the webhook address (firewall etc).

For instance, on Digital Ocean server, you would need to open up the port (mentioned in git-auto-deploy.conf.json) in the firewall:

sudo ufw allow 8866/tcp

Double-check though what you put in Manage Jenkins > Configure in term of Gitlab information (connection name, host url, credentials), as mentioned in jenkinsci/gitlab-plugin issue 391.
