HTTP Error: 400 (Bad request)

Hi. We previously had the "Abandoned transaction found - run hg recover" issue a few days ago which was fixed. (As mentioned in BCLOUD-10024, same repository)

The repository: https://bitbucket.org/plutora/portal

Now however, we are receiving a "HTTP Error: 400 (Bad request)" whenever we are trying to pull code through tortoise hg (Me and multiple developers). This may have been caused by me closing a lot of branches because it was working fine during my process of closing them, and then tried to pull again but started to receive this error. When trying to build teamcity, it does not work because of this error either.

I initially did a

#!python

'hg rollback'

on my localhost and it seemed to fix my problem, but the "HTTP Error: 400 (Bad request)" came back and we are still unable to build through teamcity.

Looking through some previous tickets, here are some information.
Using

#!python

hg pull --debug -v

, I receive:

#!python

Note: I'm still able to commit and push code.

Thanks in Advanced.
