Just popping in to say that you should find that TalkTalk Mail is now authenticating your sign in without a problem. I noticed this morning that TalkTalk Mail's mailbox authentication was taking rather longer than normal to complete. This was a mail platform issue and not something that you'd have any direct control over.
The error screen you saw was a timeout of the initial phase of authentication that presents the blue screen 'retry' message after waiting for 6 seconds for username authentication to complete. Rev69 is just the current TalkTalk Mail user interface version number.
When that blue screen appears it's usually because a user device is holding up the sign in handshake by being busy with other activity like anti-virus scanning or updating software or just waking up slowly / having a slow wi-fi connection. But in this case, because there were mail platform authentication delays accessing the mailbox server to retrieve mail messages there would have been consequential hold ups in authenticating users to the mail platform. So, today, not a specific issue for your device or the sign in to your mailbox.
Generally, the faster the user device works the less likely it is to be shown the blue time-out screen. The standard workaround for a 'slow' device or slow connection is to wait for anti virus scanning or software updating / uploading to complete on a device or just pause those activities before initiating a mailbox sign in.
Sign ins should be fast and error-free for all of your devices right now, but let us know if you still have the blue screen sign in error as you may then need to clear the browser cache and cookies before retrying. But hopefully all will be good from here on.
