My visualcron client is not connecting to the server anymore.
Here is a part of the serverlog:

Any help is appreciated. I have reinstalled visual cron and again imported my saved settings but still I get the same error.

Which version are you running?

Please test this version:

We are using the version 4.1.0.

However I managed to get it back up.
I used my old setting files(older version) to replace the current one's in the setting folder.
Then I started visual cron, and the client and it worked.
After that I imported my latest setting from may latestsettings.zip file and I was able to restore my current settings back.
According to one of my colleague the xml files may have gone bad and the import may have corrected those files. Is that really the case? What does the import exactly do?

You should upgrade to at least 4.9.40.

The import takes the file from the backup, unzips it, and reads the content (all settings). Depending on import settings VisualCron may or may not clear existing settings.
