I saw a some folders and files, in them were some .pem files. Did not investigate further..
I ended up solving my issue by completely uninstalling and reinstalling. I thought I had tried it without any luck, but I just tried again, and I can add certs now, the container is working again. Before figuring this out, I checked dynamic dns, cloudflare DNS Cnames, and my router settings, denying it was the container throwing error. I'm glad it was as simple as uninstalling and reinstalling.
Here' what I did:
-Delete container
-Delete appdata (I needed to do it through krusader)
-Delete from "previous apps" in apps tab.
-Reinstall
The first time around, I did everything except clear it from Previous Apps.
I was thinking about copying files over from old appdata folder, but this container is so easy to use, I'm just going to keep it clean and reinput all the certs and proxies again.
Hope this helps someone!
