Browserextensions - no result

I´m using the chrome and the firefox-extension, but both are not working.

After setting up URL, user and password, the connections seems to be working - but the extensions do not recognize logins nor are there any results by useing the search-box.

Any ideas what to do?

Thanks in advance!


Have you tried using the synchronize button in the top right corner?

Which version of the extension and app are you using?

I tried to syn - the arrows are turning for a few seconds without result.

We use of your extension and nextcloud 16.0.1.

This issue appeared month ago, but at now its very annoying. Therefore this post.

Maybe it lasts at nextcloud?

Today I started the developer-console on FF here are the results if I try to login:

Is any help out there?

There is two possible options i figured out for this case:

  1. You could have the “Legacy API” disabled in the admin settings
  2. Your login data is wrong (Maybe check in the settings of the app. If you used a token, remember that it will not work anymore if you changed your password)
