Upgrading SnapCenter Server on Windows to version 6.1P1 (from 5.0P2) and a couple of times during the upgrade I got a message that an Erlang OTP binary (by Ericsson AB) wanted access to the network but was blocked by the Windows firewall.
Can you tell me what this Erlang component is in the SnapCenter installer and what I am now missing since it was blocked?
The SnapCenter upgrade seems to have been successfully completed without it.

Erlang is part of the RabbitMQ messing service that transfers messages from the scheduler to the Main SC process.
You'll need to unblock those

What does it need to talk to on the network?
And perhaps the upgrade was not successful after all because the web page gives a Error 500 now.

Localhost, should be limited to ports 5672, 3306, 8154 and 8147, but that's from memory, let me look it up.
