Hi ThinkNight,

Are you still seeing this issue on OTA2?

Hi,

I haven’t seen the issue again on OTA2. However, I also made two changes to my setup:

1. switched to a wired connection instead of Wi-Fi

2. added an HDMI dummy plug

After that, the system has been stable. So I’m not sure whether OTA2 fixed it directly, or whether these two changes avoided the problem.

This issue is no more, thank you.
