I also had similar issues on iOS when I migrated to Baikal. Every other device was working fine.

Double check that your certificates are valid. I don’t remember the exact details but Apple made a few changes somewhat recently in regards of what kind of certs are accepted on their devices.

If you’re using self signed certs you have to install them manually as well, don’t forget that.

Ah, I see.

Perhaps sshfs could be an alternative. Not sure of the performance out of the box, but it is possible to tweak a bit.

NFS kinda sucks and I’m looking for alternative solution

Rsync + cron? If you just need to backup some files/directories.

Edit: ah, saw that you will read/write a lot. Do you really need to do that over the network? Why not upload a .tar, a snapshot or whatever of the changes?

If you could be a bit more specific then maybe we could give some better advice.

Use a seedbox if you’re downloading stuff and dont have enough disk space.

Maybe this can point you in the right direction.

I’m not familiar with LXC - do you put together your container from scratch kinda like a FreeBSD jail?
