Internal API unreachable

Hey Community,
I have rather interesting problem with Gitlab.
So chronologically, last Friday (read 30.11.2018) I have pushed and pulled regularly.
But as I return to my job, this Wednesday (read 5.12.2018) I couldn’t do anything.
And the error message says -
"nebo@localhost:/var/www/html/iclei$ git pull
GitLab: Failed to authorize your Git request: internal API unreachable
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists."

And also the same from the server itself.
I can’t remove it.
