Troubleshooting

SSL certificate errors

When trying to integrate GitLab with services using self-signed certificates, SSL certificate errors can occur in different parts of the application. Sidekiq is a common culprit.

There are two approaches you can take to solve this:

1. Add the root certificate to the trusted chain of the OS.
2. If using Omnibus, you can add the certificate to the GitLab trusted certificates.

OS main trusted chain

This resource has all the information you need to add a certificate to the main trusted chain.

This answer at Super User also has relevant information.

Omnibus Trusted Chain

Install the self signed certificate or custom certificate authorities in to Omnibus GitLab.

It is enough to concatenate the certificate to the main trusted certificate however it may be overwritten during upgrades:

cat jira.pem >> /opt/gitlab/embedded/ssl/certs/cacert.pem

After that restart GitLab with:

sudo gitlab-ctl restart
