Does anybody here use ownCloud?

I know it’s less popular than NextCloud, and I understand the reasons, but I’m not able to get next cloud working at the moment.

I had it working very well and sinking across my devices through tailscale. Unfortunately, after updating some contacts, the entire contact functionality seems to be frozen. I have my contacts backed up on another device, so I’m fine with wiping it and starting over, but I don’t want to erase my calendar or files that are also hosted through ownCloud.

I haven’t been able to get help on their dedicated forums, but if someone has an idea of a better place to ask, let me know.

Has anyone run into this? Do you know how to erase and reset the contact functionality in owncloud? At the moment, anytime I open up the contacts app, it just spins and spins. And external devices no longer connect. I don’t have the time to relearn a new piece of software at the moment. I suspect that any other card dav that I set up will interfere with what I currently have. I’ve read that running different software of this type from the same server can cause some issues, especially since they tend to want to use the same ports. I just want to reset the contact portion of my owncloud.

I’m running the latest version through Docker. I’m using MariaDB for my database. I’m not sure what details will be useful, but please let me know what I can supply and if necessary how to locate it. TIA
