Guests without access


After upgrading to 4857, guest access failed.

We use integration with Rocket.Chat. It is important to us that only users can create videocall, but that the invitation to videocall via link works.

Currently, after entering the link, he asks for a login and password.

Does anyone have a proven idea to configure joining to be available to guests via a link?

Which guess access? Maybe show your config?
Any errors in prosody?
