Light burn bridge stops etching mac

When I’m connected via Ethernet on my Mac it works and cuts. But now I’ve connected to light burn bridge when I etch a picture it stops after about 20%.
Any idea why?

iMac, light burn bridge, Wi-Fi router 2 metres away from raspberry pi 3+

I’m not up on Macs, but they usually ask for the basic information, such as mac OS version and the Lightburn version. I’ve been using the bridge for a couple of months, with no issues, but I run Linux.

Might want to search this forum (magnifying glass on page header) for your issue.

Good luck
