Failed to load data - wont connect to my server

[gerardvanschip-work]

The utility stopped connecting to my server since last week, I get the following error:

Failed: Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost." UserInfo={_kCFStreamErrorCodeKey=57, NSUnderlyingError=0x600001faccf0 {Error Domain=kCFErrorDomainCFNetwork Code=-1005 "(null)" UserInfo={_NSURLErrorNWPathKey=satisfied (Path is satisfied), interface: en1[802.11], ipv4, dns, uses wifi, _kCFStreamErrorCodeKey=57, _kCFStreamErrorDomainKey=1}}, _NSURLErrorFailingURLSessionTaskErrorKey=.... etc

I have tried the following:

• Delete Jamf Sync
• Delete the plist from preferences
• setup from scratch
• disabled vpn

Anyone got any idea? I only found out about this super handy utility a few months ago and its a life saver.
