Hey guys, I’m trying to install an integration with Gitlab and one of our products (Freshservice), but when we try login to Gitlab via OAuth, we get the following error:
**Client authentication failed due to unknown client, no client authentication included, or unsupported authentication method.**
I noticed that the issue happens specifically for custom GitLab domains but not with default gitlab.com domains.
Please find the screenshot attached below. Any updates/guidance regarding this would be appreciated. Can I please receive some help to resolve this issue?
