R7800 Repeating sign in requests 1.02.62

[wrswldo]

After signing into my router and turning on Dynamic QOS, trying to access Attached Devices results in a repeated request to sign in. This persists regardless whether I sign in with Admin and my password (same one I used to initially sign in) or canceling the request. If I press cancel enough times, I can get about a second of time to navigate the page before it pops up again. When I click on a device, I get taken to a password reset request. 

I'm trying to accomplish setting which devices have priority for QOS, which from research suggests this is the way to do it based on this post:

https://community.netgear.com/t5/Nighthawk-WiFi-Routers/How-to-set-qos-priority-on-R7800/td-p/133880...

If I turn off QOS then I can access the Attached Devices, though there are of course no QOS options.

Thanks in advance.

Solution is to change password to eliminate certain special characters.
