There are few post in the line of this issue, however, the cause of the problem hasn't been figured out. This occurs out of no where, I wish I was able to find device's system log that help to identify the problem. Btw, would debugging via adb devices would work, did anyone try it
I have ruled out that my connection has nothing to do with the problem. since, I have access on internet with other devices. I have static connection on the Ccgtv setup
The suggestion other has made, whether the ipv6 disabled or set to prioritize through Qos
Any idea on when google might release update to resolve the problem. the last update was in September, I have seen others having similar issue. the only solution I see there is to reset, even then I feel it can be hit or miss
Set your IP address to a fixed address in the CCwGTV settings, not DHCP. As soon as I did that, no more issues.
