MQTT connection issue with devices

So this is new and weird to me. MQTT on HA is not working.

Socket error on client Sonoff_SVGD, disconnecting.

I reverted snapshot week when it was working, no dice. I sent my tasmota devices and esphome and octoprint to a cloud mqtt to test, that works fine. So not my network/wireless. I haven’t made changes on that either lately.

So I have all these different devices and and I’ve never had this happened that reverting can’t fix.

Really? Please read this. How to help us help you - or How to ask a good question

Sorry my bad on that.

I went back to my older HA VM and updated it, and mqtt does not have this issue. Weird since the new VM was a fresh image with the older snapshot restored on it and then updated.
