I’m running OpenSUSE leap 15.5, When I was on the linux mint, I was using warpinator but using it on openSUSE is troublesome and I wish there was a linux version of blip but unfortunately there is not.
Something like this happened on my sister’s laptop. She got a new laptop with Windows 11. She followed some website to set up Syncthing, but it wasn’t syncing. Turns out, there’s some kind of “trusted network” deal that needs to be figured out. (Don’t remember the exact term anymore.) Anyway, helped her fix it, and installed Debian Stable on it the next time I was visiting.
