Continued: deploy previews with GitLab self-managed


After my previous support request, the Deploy preview collaboration worked fine for a while. However, since last week I’m seeing a slightly different issue which leaves me again unable to use this feature. Attaching a screenshot below.

A quick look at the devtools Network tab doesn’t show anything obvious (to me).

one of the URLs where this happens:

Hi @bart.brosens – sorry you’re encountering this issue! If you do see any errors > 4xx in your Network devtools, please post them here as that will help us debug together.

Speaking of debugging, could you please verify that your GitLab PAT you inputted has not expired and has not been revoked? You can check on your GL instance at the /-/profile/personal_access_tokens route.

Thanks, and please be sure to let us know!

Hi @jasonb,

Thank you for your reply.

I’ve checked my GitLab PAT which still is valid. If it would have expired, shouldn’t I see a dialog asking for a new one?

There is one 404 error in the Network devtools. I’m pasting the details below. Hope this helps!

Best regards,

Thanks for that debug info @bart.brosens! We’ve just pushed a change we believe will fix your issue. Would you mind trying again? Thanks for your patience!

Hi @jasonb ,

Thank you for the information. I confirm it’s working again!
