Could not open browser

Nextcloud version: 15.02
Operating system and version: CentOS 7.6.1810
nginx version: 1.14.2
PHP version: 7.2.14

Issue: Unable to sync my folders/files to my PC.

Is this the first time you’ve seen this error? Yes

Steps to replicate it:

  1. Trying to sync my nextcloud client to my nextcloud server
  2. Already have my folders with data sync’d from previous version, look at attached error.

The output of your Nextcloud log in Admin > Logging:

Warning Login failed: username
Warning Login failed: username
Warning Login failed: username
Warning Login failed: username
Warning Login failed: username
Warning Login failed: username
etc

Error screen:

Login works fine, btw. I’ve tested that numerous times. Browser is set, nothing wrong with it. What’s the deal?

Pls check if a default browser has been set as the message advises.

Kind regards
