It seems there are no other versions than latest in downloads, and I don’t have any old packages stored (I host it on Synology NAS for what it’s worth). However, I highly doubt incompability, as I can’t see any attempt of establishing connection when I look at logs console, it’s like client doesn’t even try to scan network… I see obvious logs whenever I connect any other device. So looks like server is not involved at all in this issue.
Furthermore, I’ve just updated from 1.16.x, which worked, and there shouldn’t be any possible compability issues between 1.18.7 and 1.18.6, according to semver, patch version (third value) is supposed to be for backwards compatible bug fixes.
It’s possible that my issue is related to this one: Plex no longer available after tv firmware update
