MQTT setup error in 43.2

Got a couple of MQTT sensors that were working fine on 43.1, just upgraded to 43.2 now getting:

This indicates a problem connecting at the os level rather than a problem with HA. Is your broker on a different machine? Can you ping that machine from the HA machine?

Thanks for the tip: I am running it on localhost but referring to it in my config via its ip. Had been pointing to the wifi ip which had changed, whilst I have a DHCP reservation on the ethernet ip… So solution is to point to my ethernet ip… Thanks!
