TeamCity - Unable to login / rest api authentication error when switching to 64bit Java Follow

Hello,

I have recently upgraded to version 9.1.1 and also switched to use 64bit Java instead of the default 32bit that comes with the windows installer of TeamCity.

But I started getting authentication errors once I have switched to use 64bit -

This error would disappear when I swtich back to using 32bit.

Is there something I have missed that needs to be set on the server to enable 64 bit to work?

But apart from the login / authentication issues, I can see that TeamCity can communicate with agents, and builds are running fine as usual when using 64 bit java, just not able to authenticate if you are not already logged into the server etc.

Have attached auth log from teamcity server.
