unable to login using gitlab.com account from git.fosscommunity.in

Could not authenticate you from GitLab because "Invalid grant: the provided authorization grant is invalid, expired, revoked, does not match the redirection uri used in the authorization request, or was issued to another client. {"error":"invalid grant","error description":"the provided authorization grant is invalid, expired, revoked, does not match the redirection uri used in the authorization request, or was issued to another client."}".

It was working earlier with 8.9.0, now we are on 8.11.3. It did not work with 8.10.5 as well. Importing from gitlab works so oauth is set correctly.
