Hi.
I tried all browsers existing, using a PC, ipad. Disabled all security features on my Wifi. Reset my homey and restored from backup. Using just cellular connection. When using tabled the site just freezes and when using Edge on a PC i get something went wrong when browsing devices.
It all happen after I moved or renamed a zone I think and there might be others with the same experience. I also had to reconnect all devices to a new zone. Might it be something to do with zones?
