Integration with TeamCity just stopped working

We had integration with TeamCity working just fine for almost a year, then I believe we changed Fixed in Build field or something like that and everything just stopped working. We reverted everything back, but now we just cannot make it work again no matter what we do.

When I "Reset" the integration and then "Run" it again I get the following errors:
