Webdav not working, keep getting the error: script '/var/www/html/remote.php' not found or unable to stat

Hi there,

Since i upgraded from Owncloud 9.0.10 to 9.1.6 i cant get webdav to work on windows.

When i check the apache2 error log i see.

script '/var/www/html/remote.php' not found or unable to stat <- this is correct because there is no owncloud installation here.

I dont have any rewrite rules on my apache2 setup so i am baffled as to where this error suddenly comes from.

Steps to reproduce

Upgrade from 9.0.10 to 9.1.6
Call for the webdav URL in windows exlorer with map drive -> https:///remote.php/webdav'
Check apache2 error log for -> script '/var/www/html/remote.php' not found or unable to stat
Expected behaviour

Show the files

Actual behaviour

Gives error upon connecting to webdav drive
