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.
Can you open owncloud in your browser? https://yourserver.com/status.php? Check your SSL configuration: ssllabs.com Are there any log entries on server side? Do you use Firewalls? If yes, please check their logfiles if they block connections.
Thanks for the suggestions. - Yes can connect via browser - ssllabs.com, Used their testing procedure and got a A-Rating - have no access to server logs at the moment - no Firewalls. Clean new install of Linux Mint 18 and ownCloud desktop client 2.2.3 - older ownCloud desktop client on my other laptop with LM 17.3 connects
But I experience some teething problems with LM 18 which gradually disappear. Maybe time will tell
If an older version of the oc-client and LM can sync, your server setup is not to blame. What would be great, if you could find out if e.g. LM 18 + OC-client 2.2.2 (or other version) works and 2.2.3 doesn't.
