431 and signin from new browser with - CAL_SIGNATURE_TOKEN needs to be set to increment usage.

When I try to sign in, I get a 431 with:

CAL_SIGNATURE_TOKEN needs to be set to increment usage.

Thanks for opening the issue. This issue seems to arise when something is wrong with the signature token environment variable. You might get faster feedback on this in the calcom repo as its most like an environment variable misconfiguration or core issue unrelated to docker.
