Running Hub 3, 25.0.3, and I have the below in my apache2 virutal host file, but for some reason Iām still getting JUST an error on nodeinfo ( Your web server is not properly set up to resolve ā/.well-known/nodeinfoā. Further information can be found in the documentation 
.)?? I donāt have a theory how the other 3 entries work but not nodeinfo?
Actually, now I see that my entries removed the errors in Firefox, but not in Chrome? Why is that?
Redirect 301 /.well-known/carddav /remote.php/dav
Redirect 301 /.well-known/caldav /remote.php/dav
Redirect 301 /.well-known/nodeinfo /index.php/.well-known/nodeinfo
Redirect 301 /.well-known/webfinger /index.php/.well-known/webfinger
I also had the same warning for nodeinfo. I fixed it by removing a small section of code in the file : /var/www/nextcloud/dist/settings-legacy-admin.js . (Other peopleās installations might not be in /var/wwwā¦)
Itās a large file, but I found and removed this code:
\n\t\t\tOC.SetupChecks.checkWellKnownUrl(āGETā, ā/.well-known/nodeinfoā, OC.theme.docPlaceholderUrl, $(ā#postsetupchecksā).data(ācheck-wellknownā) === true, [200, 404], true),
(I am not sure if itās necessary to remove the \n\t\t\t part at the beginning.)
The name of the file has the word ālegacyā in it, which makes me think itās some fossil code left over from an earlier version. In fact, it may be connected to an app or some feature of Nexcloud which I never use, but for me it did no harm. And the warning went away.
