Hello! First time here, i see people having the same issue as me. I have the Panasonic TX-L32-E30E. I had the same "Communication Error: Status 401" but was able to solve it this morning. I tried to login to a new Google/YouTube account i created but still got that error: "Bad Authentication - Login Failed". Aslo updated the firmware to v1.323 but still no luck. But then i received this message from Google:

xxxx,
Someone recently tried to use an application to sign in to your Google Account, xxxxxxx@gmail.com. We prevented the sign-in attempt in case this was a hijacker trying to access your account. Please review the details of the sign-in attempt:

IP Address: xxx.xxx.xxx.xxx (xxxxxxx.net)
Location: Unknown Location
If you do not recognize this sign-in attempt, someone else might be trying to access your account. You should sign in to your account and reset your password immediately. Find out how at http://support.google.com/accounts?p=reset_pw
If this was you, and you want to give this application access to your account, complete the troubleshooting steps listed at http://support.google.com/mail?p=client_login
Sincerely,
The Google Accounts Team
I followed the wizard to allow access to my unknown application (The Viera YouTube app) and logged in with my username and password and then it was ok! For username you need to enter the entire email address with @gmail.com and then it will work. Hope this helps.
