Bloomsky's servers have been up and down a lot lately. The company is mostly gone and some Chinese company (瞰天科技) has bought the IP. I wouldn't be surprised if it all turns off someday.
The best source of information appears this FB group: Redirecting...
There was someone posting on the FB group who had written some scripts to mimic the Bloomsky backend servers, so that you could intercept the messages coming out of the SKY and process them locally.
(as I noted above, my SKY died and I was never able to resurrect it. I replaced it with an Ambient WS-2000, which locally feeds my Hubitat via snell's driver at [PROJECT] Driver for Ambient API/Local and Ecowitt)
