The last two updates to the Plex server will not install on my QNAP NAS as the application is “unsigned”. Is this a change as all previous updates installed perfectly. I can change this setting in the QNAP but would prefer not to. What is the status of this?

While I don’t have an answer to the question of status, there are some instructions on how to install these builds here [https://support.plex.tv/articles/using-unsigned-qnap-apps/](https://support.plex.tv/articles/using-unsigned-qnap-apps/)
