Today I noticed that Telegram Notifications do no longer appear in the notification area. In addition the dash icon no longer displays the count of unread messages.
Upon opening Telegram I was prompted to log into Ubuntu One in oder to enable notifications, be reminded later or not receive notifications. I chose log into Ubuntu One, but nothing happened except the prompt closing.
As of now there are no notifications. Telegram is allowed to push notifications under System Settings > Notifications.
Is there any way to bring the prompt back or fix this manually or is this a bug introduced with a recent update of Telegram? I don't remeber it updating though.

It appears the reason was a changed password to my Ubuntu One account.
The only way to be able to re-authenticate was to delete the account and then set it up again. Notifications are working again.
Keeping this Q&A for anyone bumping into the same issue.
