Page Not Found page does not work after installing Umbraco

[nikolajlauridsen]

Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)

10.3.0/11.0.0-rc1

Bug summary

The 404 page does not work after installing Umbraco until you restart the site.

Specifics

After you've just installed Umbraco you won't get redirected to the default 404 page if you try to go to a page that does not exist, instead, you get an ERR_TOO_MANY_REDIRECTS this does, however, go away and everything works as intended after you reboot the site, so in the grand scheme of things it's not too big an issue.

Interestingly the "No Nodes Found" page still works, so to see the error you have to publish a piece of content, otherwise, you'll just get redirected to the "No Nodes Found" page.

Steps to reproduce

1. Run a fresh site and install Umbraco but DON'T restart the site
2. Create any piece of routed content
3. Try to go to a page that does not exist

Expected result / actual result

Expected result: A 404 page should be shown

Actual result: an ERR_TOO_MANY_REDIRECTS occurs

Wonder if this is because the installer still kicks in somehow

[nikolajlauridsen]

Yeah, I'm suspecting it might have something to do with our catch all fallback route we use when installing

Possibly related to #13309 which is marked as sprint candidate, so I'll hold off doing too much with this one

Fixed in #13551
