So i managed to isolate the issue in one scenario.
This happens only when the edge is connected in a different network than the VCO and VGO.
When i connect the edge to the same network as VCO and VGO , everything works fine.
When i connect the edge with 2 interfaces , one in the same network as VCO and VCG and another in a different network, it works.
It only doesn't work when all interfaces are in a different network than VCO and VCG , despite activated correctly.
