Anyone any more ideas here? Servers not visible to certain group members through visible to others on central server. As I understand from what I've read elsewhere here the client sends a UDP ping to the server. Is this a general or a Jamulus packet to specific port? Trying to establish if a standard (ICMP) ping can test this. If so would you use the IP address that you can find by going to, eg., https://whatismyipaddress.com/ from the server? Grateful for any other suggestions.

Small thing, but I have KeePass minimise after opening database (Tools-Options-Interface)...
