Onkyo platform stopped working

My Onkyo platform has been working fine but not today.
Anyone else having problems?

Same. I noticed it not working a couple weeks ago and just haven’t got around to running onkyo-eiscp to debug. I have a TX-NR646 and HA version 0.110.4

Yesterday I tried rebooting my router to no avail (I could still ping the receiver) so this morning I turned off the power to it and then after power on it works again.

Look at that! Unplugged receiver for a bit, and then plugged it back in. Worked like a charm! Thanks @robfish for the tip.
