In my situation we have a website which was DNN version 9.2.1 and because of the 404 page bug we updated to DNN version 9.3.2.
This should have resolved the issue but still it gives us the same error. A 503 site not found error as seen below:

Does someone know this issue and how to resolve it?

We have tried the following:

  1. Run this SQL to fix which was in one of the other forums:
    Update HostSettings SET HostSettings.ControlPanel = ‘DesktopModules/Admin/Dnn.PersonaBar/UserControls/PersonaBarContainer.ascx’ WHERE HostSettings.SettingName = ‘ControlPanel’; 
  2. Reset the setting and define the pages once more.

On what DNN version was the site created, on 9.2.1 or an earlier version?
To me this sounds like a redirect loop, did you check the TabUrls table for duplicate names (of the 404 page)
Did you try naming the 404 page differently?
I guess not, but no Ifinity URL master installed, right (check the web.config)?

In addition to what Timo suggested, I'd also suggest checking the web.config and SiteUrls.config for any other URL/rewrite rules that may be getting into the way. Finally, the built-in regular expressions used may have been changed at some point. You may want to compare those to a clean installation to see what may have been changed.

We did not find the cause of the issue, however we did find a solution. We added the following to the web.config file to properly redirect to the error page.

<system.web>
<customErrors defaultRedirect="/helaas" mode="RemoteOnly">
<error statusCode="503" redirect="/error-page?503"/>
<error statusCode="404" redirect="/error-page?404"/>
<!--/customErrors>
<!--</system.web>
<system.webServer>
<httpErrors errorMode="Custom" existingResponse="Replace" >
<remove statusCode="404" subStatusCode="-1" />
<error statusCode="404" responseMode="ExecuteURL" path="/error-page?404" />
<remove statusCode="500" subStatusCode="-1" />
<error statusCode="500" responseMode="ExecuteURL" path="/error-page?500" />
<remove statusCode="503" subStatusCode="-1" />
<error statusCode="503" responseMode="ExecuteURL" path="/error-page?503" />
<!--/httpErrors>
<!--/system.webServer>

Edit: It's not allowing me to properly paste the closing tags, but I think you get the idea

Did you try any of the posted suggestion? And if you did what was the result?
I think it's weird that editing the web.config fixes this TBH.
