Hi,
I can’t use git push and this is the error message with more relative clues for investigate this case. The feature of the gitea is that I set htpasswd with basic authentication for usage.
I found there is a slight different in the failure message-“remote: invalid credentials”. 
remote: invalid credentials
fatal: Authentication failed for ‘http://example.com/gitea_user/gitea_repo.git’
If I use none of the user inside of the htpasswd, of course, it has the the same message because of the Authentication. But, there isn’t the failure message-“remote: invalid credentials”.
I can use git clone and browser visiting to site.
This is app.ini file.
