502 proxy error

[Navadeep]

Hi Atlassians,

I was trying to resolve issue related to "Collaborative Editing" and  I requested my Linux admin to open port 8091 for this purpose.

Not sure suddenly I am not able to access the confluence application from UI.

==============================================

Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /.

Reason: Error reading from remote server

==============================================

Is this issue something related to application level ? or Network level ?

Please advice on how to troubleshoot this issue.

Best Regards,

Nav
