New install of Linux Mint 18 with all updates and ownCloud Desktop-Client 2.2.3.
When I enter the Server Address immediately (despite slow connection) error "Failed to connect to Ownclout at https://....... /status.php. Host ssl account not found"
It is not a problem with the remote server as I am able to connect via Browser and another computer running a older version of ownCloud-Desktop-Client through the same router.
In another post a user suspected a time-out but solved the problem by discovering a DNS-problem. I asked my provider to check my DNS-settings but they are correct.
Must be eighter the client or LM18. Any advice?
