While doing the modification on the Installed Applications it’s getting 502 error

Hi,

 

After upgrading FNMS 2020R1 we have observed that any changes done on the Installed Applications . we are facing issue while trying to save getting below error. This is On-Prim Solution. Attached screen shot.

"502 - Web server received an invalid response while acting as a gateway or proxy server.
There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server"

Thanks,

Sreerama Yenuga

Can you check this IIS logs, maybe enable Failed Request Tracing and check those logs too, for a more specific error?

Hi,

I cannot see anything obvious, you should open a support case for this issue.

Best regards,

Hi,

Increase the Time out session. Now it's working fine as expected.

Thanks,
