Hi, my office cannot access any zoom relate app or website. Only show ERR_CONNECTION_RESET in Chrome.
In app it show error code:1005456000
But when connect to another network, everything works.
We checked zoom ip and port list here
But all I see in firewall outbound are using port 137 which is not listed in required port. So, it all deny.
Example below are outbound IP and port that firewall deny during testing.
Some are Zoom IP with wrong port but I'm not sure about others.
40.126.53.24:137
51.141.119.73:137
52.109.89.119:137
52.109.44.112:137
52.184.217.56:137

Please tell me what to check further.

Zoom requires specific ports and IP ranges to be allowed through the firewall for its services to function properly. Ports 443/TCP and 8801-8810/TCP are commonly used for Zoom meetings.
