Hi there! I see your rigs are not working with the NiceHash app. I want to make sure I understand the situation clearly—are the rigs not showing up at all, are they offline, or are they running but not mining correctly? Also, are you using NiceHash QuickMiner, Miner, or NiceHash OS? Knowing this will help me guide you better.

While you get that info to me, here are some basic steps to start troubleshooting:

1. Check Internet Connection: Make sure your rigs are connected to the internet. If the rig can't access the internet, it won’t communicate with NiceHash services properly.

2. Verify Miner Status: On your rigs, check if the mining software is running and stable. Sometimes miners crash or restart frequently due to GPU or overclocking issues.

3. USB PCIe Risers: If you are using rigs with risers (hardware to connect GPUs), defective risers cause the rig to not detect GPUs properly. Testing or replacing risers is a common fix for rigs not working1.

4. Notifications & Rig Manager: In your NiceHash account, you can enable rig notifications and check status via the NiceHash Rig Manager online dashboard to see if the rigs show as online or unmanaged2.

5. System Settings: Make sure no firewall or antivirus is blocking NiceHash mining software. Also, check your BIOS settings if you’re using NiceHash OS—setting boot mode to Legacy is sometimes required5 9.

Could you also tell me:
- Are any error messages showing in the app or on the rigs?
- Have you tried restarting the rigs and your router/modem?
- Which version of the app or miner are you running?

From there, I can walk you through more detailed steps!
