Hello,
I have also "import neighbours" issue.
A brief description of the situation.
3 spaceLYnk installed (1x, 2x, 3x)
I can export objects from 2x --> 1x & 3x BUT when exporting any objects from 1x --> 3x OR 3x --> 1x , then an error is shown:
Import result/ Error: 401
The password is correct.
Objects are real (not virtual).
Neighbors are on the same network and visible.
