Issue: While login Cloud Client shows message "Configure a web proxy to sign in to the service" even if port 35061 TCP and 443 TCP are opened on Firewall.


Analysis: This message should appear only when port 35061 TCP and 443 TCP are closed on customer Firewall.



Step-1: Verify if these ports are open from customer PC: Open command prompt on PC and telnet Lifesize Cloud server IPs with port 35061 and then 443.

Note: You can find Lifesize Cloud server IPs at Lifesize Manage Console ---> Advanced settings ---> Network ---> Node Address


If you see, "connect failed" message on Command Prompt then contact Firewall team to open these ports towards Lifesize Cloud node IPs.




Step-2: If you see ports are open then Anti-Virus installed on customer PC is blocking TCP connection from Lifesize Cloud Client.


Resolution: Login to Anti-Virus UI and add "Lifesize Cloud Client" as trusted application. Once done, exit Lifesize Cloud client and open again. Try to login and it should login successfully.
