GitLab | Registry Login Error Parsing Http 403 Response

February 27, 2021

Question

Sometimes error messages very hard to understand

$ docker login registry.gitlab.com
Authenticating with existing credentials...
Login did not succeed, error: Error response from daemon: Get https://registry.gitlab.com/v2/: error parsing HTTP 403 response body: unexpected end of JSON input: ""

Answer

After digging through search results which weren’t relevant and didn’t help I found this https://gitlab.com/gitlab-org/gitlab/-/issues/207509

Turns out the issue was due to IP blocking. VPN solved this without problem.

What I Learned

If you have 2FA enabled your regular login and password wouldn’t work.
If you have Two-Factor Authentication enabled, use a Personal Access Token instead of a password.
