No Guide, now no DVR

Everything was going great, but in the last few days I noticed that the guide was not being updated, and so I thought a server update might be a fix. Now with the current build (1.8.0.4109) the Plex DVR was not set up, and the program cannot locate the HDHomeRun on the network, even when I type in the IP address manually (and yes it is working).

Tried a complete reinstall, but still nothing. Any ideas?

Have you tried manually refreshing the channel guide?

I cannot even get to this screen…the HDHomeRun cannot be located on the network. It is so weird as it was all working fine up until a few days ago, and this runs on a server I do not normally touch. I can thouhg watch TV from the same server using the HDHomerun Ap.

As a postscript, I just realised that if I enter the IP address, the continue button is enabled (even though the name of the device is not displayed) and I can complete the setup EXCEPT that Plex still does not believe I have a tuner installed.
