Screenshot of the problem in Start Center

When a remote NextCloud is attached in Windows Explorer, trying to open files from it causes an error message saying “$file does not exist” while it definitely exists.
This does not happen with Nautilus on Ubuntu 18.04.

Steps to reproduce:
    1. Attach a remote NextCloud storage in Windows Explorer. I named ours share.allotropia.de
    2. Try to open a document from it with the normal File dialog or DnD (NOT Remote Files)

Actual results:
\\share.allotropia.deshare.allotropia.de@SSL\DavWWWRoot\remote.php\dav\files\gabor.kelemen.extern@allotropia.de\Documents\lorem-73.odt does not exist.

Expected results:
File opens.

The bibisected "first bad commit" does not necessarily mean that it *is* the real bad commit which broke this, but the bad commit should be in the good..bad range.

Could you please attach your bibisect log (git bisect log)?
Comment 2 Kevin Suo 2021-12-23 10:11:33 UTC 
But anyway, commit 0b46361ef84a61100a0274a007062317607d097a is a possibility as it relates to INetURLObject::parseHost.
