Mail App not working under Nextcloud 17.0.0

[hillebr]

Expected behavior

Maill app stopped loading Mails on all added accounts after update to Nextcloud 17.0.0
Removing and re-adding the app won't solve the issue
When starting the app, the circle keeps spinning an nothing happens (see attached schreenshot)

and the following error shows up in log:

Exception: The requested uri(/index.php/apps/mail/api/accounts/20/folders/SU5CT1g%3D/messages) cannot be processed by the script '/nextcloud/index.php')

/var/www/html/nextcloud/lib/base.php - line 943:

OC\AppFramework\Http\Request->getRawPathInfo()

/var/www/html/nextcloud/index.php - line 42:

Related to nextcloud/server#11913 CarnetApp/CarnetNextcloud#14. Do you use that app?

[hillebr]

No, I do not use the carnet app and I never did before.

[ChristophWurst]

This is strange. I have never seen an error like this. Could you temporarily disable other 3rdparty apps?

[hillebr]

I did but the issue is the same - even after reinstalling the Mail-App.
Maybe I have to reinstall my NC instance.
Could this error be related with a broken webbased update to 17.0.0?
After updating the files the webbased upgrade failed with a white browser tab.
I had to finish it with: sudo -u www-data php updater.phar
After that NC was running again except the Mail app...

[ChristophWurst]

Any warning on your admin settings overview page? Does the integrity check pass?

[hillebr]

...no warnings and yes, the check did pass!

[hillebr]

Hi there,
after update to Nextcloud 17.0.1.1 the issue is fixed!

Thanks a lot!
