Hello everyone! Read about 10 topics with this problem - nothing helped me to solve my problem. I have message in LightBurn - No laser Connected. I got Raspberry 3b+, and Ruida 6445S controller. One router in room with one laptop on wifi and raspberry on it.

What i did:
- Re-installed image on raspberry 3 times
- Tried 4 different ethernet cables (5, 5e, 6 CAT)
- Tried different IP addresses (just in case)
- Tried to connect from extension port and from ruida controller
What I cant check - if my controller fault. But its brand new. And I can connect and control it with computer<->controller direct ethernet connection from LightBurn.
One thing that bothers me - on my raspberry pi always lights only one green light (solid or blinking), so no orange light. But this raspberry was fully functional last time I used it (for my smart home system).
And I can’t check if it’s possible to ping controller from bridge because i don’t know credentials for SSH (tried - root/root root/admin admin/root and pi/root and all combinations).
Any ideas? 
Still can’t connect Bridge to my laser
