Hello @6hil

Please include which version of cyberpanel you are using as instructed here How to ask for assistance?

@josephgodwinke it is Cyberpanel V2. 3.3

Just point that subdomain to that other server IP

hello @Dreamer thank you for your reply. I have added the IP address like you said. I can ping the subdomain and get answer for dig command as well.
theissue i am facing is when i enter the subdomain in the web browser i can’t access the app i have installed and for whitch i want to point the subdomain in the server. The app is installed on that second server. Entering public IP and port get me to the app.
Any taught?
Thanks in advance.
