I am self-hosting an Apache2 setup using on a Debian server with a domain which is linked to an ip connected by AT&t Passthrough. I have an SSL cert from Certbot and firewall setup for port 443, and 80 for CasaOS which is connected to a TailScale VPN. )The TailScale is only linked to port 80 and CasaOS, but I thought important to mention because Apache can use Port 80)

I have DAV_SSL enabled on my system, and consistently connect to the domain on a browser using https.
Tortoise SVN on my local windows machine is able to checkout into a folder, but when attempting to commit it will add the changes, then freeze before uploading – or if it does upload, it will stop part-way through.
Using svnadmin, it says it cannot access the format file within the repository folder.

I am on Debian 12.6 (using only terminal – no GUI) and Apache 2.4.

I have tried adding Apache (www-data on Debian) as an owner of the Parent path (/var/svn) and of the singular repository (/var/svn/TestRepo).
ls tells me that www-data owns the directories, but svnadmin can’t access the file and commits won’t work.

This screenshot drives me mad – it shows the security of files are set and ready, but it just won’t work.
some bull from linux

I have redone the certification as AT&T said it was bad, reconfigured the firewall, relocated the SVN Parent Path from /svn to /var/svn (and subsequently changed the apache.conf file).
I am going absolutely insane. Please help me.
