gns3server.ubridge.ubridge_error.UbridgeError: could not complete netlink transaction

[ChenFryd]

Hello everyone.
When starting a docker container in GNS3 I get an error:

Internal server error http://127.0.0.1:3080/v2/compute/projects/208df4cd-8e1f-4b12-b6fd-8f3bf3c2d72f/docker/nodes/97a6d47b-3121-414b-bf06-deab6d3e8cd4/start

In the GNS3 server I get:
