Support Bug Reports
1

I created a application in our self hosted gitlab with the following settings but when i try to connect my user I get the high volume rate limit error
As you can see it seems to be error 13 in the console.
I do have a teams account and could not find any solution on the forums besides just keep trying.

Hi @Joshua_Rubin!

Have you made sure the IP addresses listed here can communicate with your self-hosted Gitlab instance?

Thanks, Colin. Support confirmed our connection failed because our self-hosted GitLab isn’t publicly accessible, which prevents Cursor’s OAuth exchange and triggers a 500 reachability error (rather than a rate limit or configuration issue).

For others: if you see a 500 error on a private GitLab instance, it is a reachability block, not an OAuth misconfiguration.
