Cannot update private key

[JMBokhorst]

Hello,

After some trouble on the server, where the harddisk was full, I repaired nextcloud though the command line (sudo -u www-data php occ maintenance:repair). However this resulted in an error that I cannot resolve:

Invalid private key for encryption app. Please update your private key password in your personal settings to recover access to your encrypted files.

When trying to update the key through the personal settings, while the screen shows 'saving...' it doesn't proceed. There are no errors in the nextcloud-log file or apache error log.

I do receive an error with the developer tools:
Failed to load resource: the server responded with a status of 503 (Service Unavailable) https://owncloud.bokhorst.info/index.php/apps/encryption/ajax/updatePrivateKeyPassword

SyntaxError: JSON Parse error: Unrecognized token '<' parse -- settings-personal.js:22
parse -- settings-personal:22
(anonymous function) -- settings-personal.js:22
j -- core.js:2:27740
fireWith -- core.js:2:27740
x -- core.js:4:11289
(anonymous function) -- core.js:4:14767

Steps to reproduce (found this one a bit difficult because the harddisk was full first):
1: Repair OCC through command line.
2: Go to installation and found that the private key doesn't match anymore
3: Go to personal settings and try to update encryption password
4: Click on 'update Private key password'

Expected behaviour

After clicking the button the password should be updated

Actual behaviour

Nothing happens and I see the error:
Failed to load resource: the server responded with a status of 503 (Service Unavailable) https://owncloud.bokhorst.info/index.php/apps/encryption/ajax/updatePrivateKeyPassword

I would like to note that I am also seeing this same bug using v13 b2 on Ubuntu Artful and nginx 1.12.1. In my case I activated the encryption plugin after adding some users.

[schiessle]

can't reproduce it. Feel free to re-open if this is still an issue with the latest version of Nextcloud

I'm also getting this when trying to update the password:
