I set up the Cloudflare access with email restrictions, so users need to enter their email, get a code and then are granted access to our website (actually, the Typo3 admin page).
I did set up a passthrough instruction for certain IPs as well.
This is working for all users but for one. This person isn’t presented with the login screen but sees the T3-Login page right away (he shouldn’t he’s not in the passthrough IP-Range).
He can login but then do nothing (the login screen keeps popping up).
I’m aware that this is most like not a Cloudflare related problem, but maybe someone here has an idea what goes wrong.
