503 on http-bind after prosody upgrade


after updating Prosody through apt I cannot start any meetings. I found the hint to downgrade to Prosody 0.11 on Ubuntu 18.04 and to set storage = "null" on configs where there used to be storage="none". Did both to no avail. I don’t get any log entries other than “client connected” and “client disconnected”. Error log does not log anything.

What’s wrong?

If you are using prosody 0.11 all occurrences need to be storage = "memory".
