On my above mentioned QNAP NAS roon is not shown in the QNAP app center. Using the website based app center roon is only listet until QTS 5.0.1, installing this package called 2021-10-03 seems to work, but when trying to open roon just a blank white windows appears. Using the latest qpkg from roononnas.org called 22-11-29 leeds to the same result.
Be aware, it’s impossible to access the roon server log files, since it’s only accessable by the configuration panel, which does not load.
If you‘d checked the requirements before posting: it does. If you‘d have read my post carefully you might have noticed, that until qts 5.1.0 Roon is officially offered, so your comment generally correct, but specifically useless.
To me it looks like the app needs an update to be able to run on 5.1.0, for whatever reason.
