Self-Managed Gitlab - cannot clone repo

Hi There - I am wondering if you can help me with this issue.

I have to setup the Gitlab self managed connection for our team but I am running into an issue in that netlify seems unable to clone any of the repos correctly.

I cannot find any errors in the gitlab logs - am hoping a support engineer might be able to help me here.

This is the log from the deploy below. I can see that netlify is able to add the deploy key to the repo but seems to be unable to clone it.

The gitlab instance can be connected to from the internet. We already use NetlifyCMS with a repo there.

Thanks in advance for your help!

hey there, sorry to be slow to get back to you. Are you still having this issue?
