Hi,
which application and version?
What you have changed?
Try to reload the page
Use another Browser
Clear cache of your Browser
DNS Issue .. maybe flush your DNS Data
Have a look on your proxy and Firewall
Check your log files
We are using 9.18 SLM version and we have not made any changes. It just started.
Tried your suggestion but still we are facing the same issue.
Was it working before or is it a fresh install?
Is it broken for all clients?
It was working fine before just today itself we are facing this issue and getting below error:
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.
Do you have a load balancer or reverse proxy in front of your SLM application server?
This is a response from something else prior to it getting to the SLM IIS side of things.
