I want to report I’m also having similar issues as everyone else. In my case I’m using cloudflares 1.1.1.2 and 1.0.0.2 dns addresses with DNS over TLS on port 853 setup in my router/firewall. I also include quad9 as well on port 853. Anything not routing DNS over TLS is blocked. I am showing my internal gateway as the top listed DNS server and hubitat cloud is connected successfully however from the network tools I am unable to ping hubitat.com. Another computer on the same vlan with dns only using the internal gateway can ping hubitat.com without issue. DHCP is enabled on my hub with a Static IP for each hub in my router/firewall set. On latest firmware.
