been away from home for a bit, finally had the chance to update my roon server (Linux) from 1448 to 1460, and this seems to have forced a logout – after updating the server software roon desktop acted as if the server was a fresh install, and asked me to log in again (and deauthorize the “old” server with the same hostname, etc). After doing so, everything seemed fine, however (library was still in place, etc).
Unfortunately, this meant that ARC on my phone thought that the server had disappeared, and that I needed to choose a new server, which forced clearing downloads, which was kind of annoying. It was, however, able to connect and everything fine after that, just as if it were connecting to a new server.
