signup_closed

Signup is by invitation. Answered with 403.

What it means

The deployment is not open for registration. No Org exists for the address, and the request carried no invite code or not the right one. The two are one refusal on purpose: distinguishing them would tell whoever is guessing whether the shape of their guess was right.

What to do

Send the invite code you were given as invite_code. Nothing else opens signup, and retrying without one will not. Signing in to an Org that already exists never needs a code.
