504 Gateway Timeout in FortiPAM

[user1111]

Hi everyone,

I’m encountering a 504 Gateway Timeout error when trying to access a FortiGate firewall through FortiPAM. The error states:

Remote server did not respond to the proxy.

I’m using the proxy feature in FortiPAM, which listens on port 8080.
The FortiGate Web GUI is configured to run on a custom port, and I’ve specified that port in the URL while accessing it through FortiPAM.

Has anyone experienced a similar issue or have any suggestions on how to troubleshoot this?
Any help would be appreciated!

Thanks!

Hi

Can you ping the configured FGT IP from FortiPAM?

[user1111]

Yes, when i allow all ports and services .
I am facing the gateway issue with porxy mode when i allow only few ports/services
Currently, the services and ports I have allowed are:

Ping, HTTP, HTTPS, FortiGate Firewall GUI port, DNS (TCP and UDP 53), Proxy port (8080)

However, if I allow all port or service, I’m able to access the device without any issues.
Am I missing any specific ports that need to be allowed for proper gateway functionality in proxy mode?
