Data map[error:API V3 is no longer supported. Use API V4 instead.]
Docker image has been running for quite some time, was broken by latest upgrade on our self-hosted gitlab-ce.
The sign in apparently works ok but then brings the user to the sign in page again.
In gitlab-ce logs we can find the message reported in the Issue title, that is quite adamant about where the problem is.
Meanwhile, the latest docker image dated 2 years ago.
Is this project even alive?
