Issue with TightVNC Connection via Guest User in FortiPAM

Dear Technical Team,

I am writing to report an issue regarding TightVNC connections established through FortiPAM when using a guest user account.

Issue Description
When attempting to initiate a TightVNC session via FortiPAM using a configured guest user, the connection fails to establish. "connection has been gracefully closed".
Normally we succeeded in web VNC. But we face issue while using TightVNC with guest user.

Environment Details
FortiPAM Version: 1.8

Could you please assist in verifying if there are known bugs regarding guest user token lifetimes, or specific configuration policies required to allow guest access for VNC proxies in this firmware version?

Looking forward to your guidance.

Best regards,

Hi Dev

Did you try with other VNC client (e.g. Remmina, TigetVNC, ...)?

Also you may check in the client logs and PAM logs (enable debug if required) to see if there are further related logs.
