We are facing an issue where the Clientless/GP Portal does not show the login page on the browser.
When traffic reaches the external firewall, we see the connection being allowed. We are using the Go Daddy cert and have ensured the cert chain is complete on the firewall.
The strange part is it works if we use GP Client we can connect to GP Portal just fine but it's clientless and web portal that is not loading and the browser gives us the error:
ERR_EMPTY_RESPONSE
This page isn’t working right now.
"Portal address" didn’t send any data.
Curl Shows: Curl Error 56 "Failure when receiving data from the peer"
The PANOS version is 10.2.9-h1, we can see all public IPs coming to the portal and the connection is ending with reason TCP-FIN.
We have already tried restarting the web-related process, and "sslmgr" process does not seem to help.
What can we do or if we need to restart the process related to GP/Clientless VPN in Palo.
Would appreciate any suggestions.
