After Cyberpanel updated to 2.1 version,.All outgoing connections have stopped

After the cyberpanel got updated, My sites are not connecting to wordpress servers, The issue SSL is also not working,. Basically users can see my website, but the website cannot connect to any server. My cyberpanel is installed on a VPS.

Anything on logs?
Try restart first. If that wont help then disable firewall and modsec to see if those blocking.
