Yeah, the weird filenames bothers me, too. It does take a hit to data portability, for sure. I’m not using it for some kind of long-term, bomb-proof YouTube archiving, but more to have offline access to instructional videos I might need in the near future. For that, the UI and integration with Jellyfin works well for me.
If I was actually collecting youtube videos, I would go with something else that generates human-friendly folders and filenames! I’ll bookmark Tubesync :)
Can you confirm that there are no spaces before or after the key on the client end? Sometimes, copy and pasting can add extra spaces that cause invalid passwords, etc.
I’m not having issues running my self-hosted Rustdesk (docker) externally, but I can’t offer much more than that :(
