Switchbot Bluetooth curtains connect but won't let me control

I recently changed hardware for my Unraid server, where I run HomeAssistant in a VM. This was similar to my previous server, until I upgraded a day ago. I restored HomeAssistant on my new server, and most things seem to work as usual.

The problem is that for my Switchbot curtains, I can connect to them via Bluetooth to see all their statistics but I can no longer control them from HA. Any time I try to set the cover level, I get an error:

Failed to perform the action cover/set_cover_position. EF-1 C-7 5-
BD-54-0C (EF:1C:75:BD:54:0C) -EF:1C:75:BD:54:0C: Failed to
connect after 9 attempt(s): TimeoutError

Has anyone dealt with this issue before? Not sure how to solve it. I've already factory reset the curtains a couple times but this issue still persists.
