I’ve updated to OH 5.1.2 on Ubuntu and confirm that ambient weather data is now being received.
Thanks to all of you working on this problem. 
I’m receiving data again with OH 5.1.2. Thank you!
Glad it is working again.
@mhilbush Got it working again after OH 5.1.2.
OT: BTW, I knew I recognized your name. I worked at IS Maryland in Timonium for 16 years (23 years overall in the said company until layoffs). Cheers
Wow, yeah, I retired in 2016. Been working on openHAB ever since. What did you work on?
