I restarted my Power Apps portal which was working fine and when I restarted it I got a 502 server error. I've pasted the error below. I've tried restarting the server multiple times but the error still remains. The only major thing I changed was adding a new image resource to a web form. I don't see why that should influence the root site. Any ideas how to fix this issue?

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.

Hi @Anonymous ,

Check this blog: PowerApps Portal Force Restart

The Restart command is basically sending an IISRESET command to the Azure App Service powering the portal behind the scenes. then your portal may face a 503 or 502 error.

The evasive technique is to actually turn off the portal and then turn it back on. Effectively doing an IIS STOP and then IIS START.

You can actually do this from the PowerApps Portals admin center, Portal Details, scroll to the bottom and see the Change Portal State.

Now select the Off state, and select Update.

Navigate to your portal and wait to receive the App Stopped message screen.

Once you see this screen, switch back to the Portal Details, select the On state and select Update.

Hope this helps.
