Can someone help me? We had our Nest Duo doing video calls, however recently in our aged care home the IT changed their firewall and since then I get a black screen when I make a call or someone tries to call me.
IT have opened the following ports but no luck, they are using a Watchguard firewall. Does anyone know what ports need to be opened for the Nest Duo Video / Voice calls to work?
Is there any official ports that we should be using for this? I can't find anything on the Internet.
Thanks for visiting the Google Nest Community.
