# below does not work, still tries to access session 1
Task.set_credentials(

Thanks @<1523701087100473344:profile|SuccessfulKoala55> , when calling this _set_default_session , I still get the error in the second call:

clearml.backend_api.session.session.LoginError: Failed getting token (error 401 from <server_1_path>): Unauthorized (invalid credentials) (failed to locate provided credentials)

This implies that there is still caching because the second call is still trying to access the first server path.

Hi @<1889122160853651456:profile|StoutArcticwolf12> , try adding this before the second set_credentials() :

from clearml.backend_interface.base import InterfaceBase
InterfaceBase._set_default_session(None)

@<1523701435869433856:profile|SmugDolphin23> This is what I mentioned today
