Cannot clone one project from Gitlab

I have free account with many private projects. From some time I cannot clone any branch of one project which is bigger than others but I don’t think it exceeds 10GB.
I try to make a clone
git clone htpps:url
with no success. I am asked for user name then for password and nothing happen. Command stucks. I can only press CTRL-C.
Other projects can be cloned, pulled/pushed.
Before this problem I created new branch inside project.
What should I check if I reached some limitations?
What is wrong?
