@cyan quest Sorry for pinging
Do you have any ideas why this is happening?
Suddenly stopped working means something changed somewhere. I'd have no idea since I can't reproduce, and lots of people use discovery without issue as long as ports and firewall rules are right.
How can I check they are set correctly?
Open Incoming rules on whatever computer is the server and ensure that it has rules that allow TCP and UDP on both the game port and the discovery port you have in Network Discovery component...default is 7777 and 47777 respectively. Ensure that computer hasn't been put into lockdown state blocking all incoming connections, either by firewall or antivirus. Note that Deny rules always take precedent over Allow rules, so look for contravening Deny rules being enabled.
You can ask any AI for detailed steps of where to look and what to look for.
