None of my dashboards will load for my Open Spot 3 and open spot 4 pro.
I have been an open spot user for a couple of years never have had this happen before.
Login page will load that will not connect.
What status LED color do you see on the devices?
Slow flashing green, the call signs are showing up on the radios and everything is working fine except cannot load dashboards on my iPhones and iPads.
I had the same issue.
Try re-connecting using the QR Code.
When you get the login page, but no dashboard after entering the correct password, just the login page again. Then delete all cookies from your browser. Worked for me.
