MCP Sign-in errors

When trying to use UE5.8.1, i am continuously prompted to do a security check both on the tutorial sign in page and in the ai assistant. When I click “verify you are human”, it just reloads the security check. As a result I am fully unable to use any MCP functions or web functions.

I CAN sign into the fab store from within UE, so it’s not a network issue. Any ideas?
