PSA: Dealing with Invalid Token

[antifob]

I've had the EteSync client fail to sync contacts and calendars for a few weeks with the "Authentication failed" message. When trying to access the "dashboard" (account -> settings -> account dashboard), the app would simply popup with "Invalid token".

This error has been encountered by others in the past years, causing data loss:
#189
#186
#119

Here says to logout, but there's no "logout" function. Searching for code with logout functionality points to 5857ed5 which is part of the deleteAccount method.

Deleting an account would delete all unsynchronized data on the device.

Here's a workaround: changing the encryption password will force the app to re-acquire a token.
I didn't check why the old password (token?) was accepted while doing the change, but hey..

Thanks for the writeup!

Thanks @antifob , that saved my day. I wrote up a page on the server wiki as I discovered my wife's phone was having issues through the logs, so it might help some admins.
