Hello All.
I have some challenges getting the sharepoint input tool to connect to sharepoint.
These are the circumstances:
1). Working from on-site: When i am working from my company, i can connect to sharepoint lists through the input tool.
2): working from home: When working from home, i get the following error.
In both scenarios i am using the same credentials to connect. (An account set up for the purpose.)

In scenario 1, i am on the company WiFi and everything works fine, i can read and write to the sharepoint lists.
In scenario two, i am working from home and connecting through the company VPN and i get the error from the picture.
If i disable the VPN i get the same error. (if im using my private computer without VPN i get the same error).
However i can connect to the sharepoint site without problems in the browser with VPN both enabled and disabled (on both computers from home).
There seems to be no difference in the firewall and network traffic wether i connect from home or from on-site.
Any suggestions would be appreciated
best regards Simon.
