Help with fire TV authentication fail

[Tata123]

My Fire TV was working fine a
Week ago I turn on today and
When Pvr is starting it shows authentication fail
I had it all good like 3 days ago
Even the guide was fine
Did something chage ? Or do we need to redo the hole settings again ?

Try to reset you route and see if that helps, I had some "authentication fail" two days ago when they were doing some maintenance on the servers.
