Gitlab "push" problem

I have problem with “git push -u origin master”.
When I try perform push, I get the following result:

git push -u origin master
Username for '':
Password for '':

Writing objects: 100% (3/3), 771 bytes | 0 bytes/s, done.
Total 3 (delta 0), reused 0 (delta 0)

and nothing else happens.

Any ideas what could be problem? I will be grateful to any advice.
