Cannot push tag to remote no more connections allowed

[dev_graduan]

As stated in question, I cannot push my local tag to remote, I'm using both source tree and terminal to push tag to remote but it's not working.

Command I used :git push origin 3.6

Here is the error log

Em.. maybe bitbucket server issue? If that so, we cannot do anything then. By the way, this problem only last a while, like 2-3 hour, after that I can push back like usual.
