How to fix 'all jobs failing' error on Windows

Windows
#1

If you are seeing ERROR (all jobs failing) Please first check the following:

  1. Make sure your antivirus is set up correctly, including windows defender. Instructions can be found here: How to whitelist Cudo Miner in your Antivirus/Antimalware tool on Windows?

  2. If your card is under 5GB, then you can only have ETC and BTG enabled, updated T-Rex miners are also being tested so RVN can be a more reliable option as well.

  3. If your card is under 4GB then you can only have BTG enabled.

Please note None of the above-mentioned coins are currently payout coins, be sure to enable ‘auto-exchange mined coins’ on the web dashboard under Settings > Payment or by following this link https://console.cudominer.com/settings/payment .

  1. If your card is under 2GB, you can only mine with CPU (monero).

  2. Some cards require overclocking enabled in the settings, keep in mind enabled doesn’t mean in use, as long as you leave the settings as default, you won’t actually be overclocking.

  3. If the card is 6GB or more, try setting the phoenix version from automatic to 5.5b, under advanced GPU settings on the main tab.

  4. If you are running multiple GPU’s on windows, you may need to set the system to use more of your storage space as virtual memory, we have a guide for that here:

  • When mining on Windows, you must have enough virtual memory even on a 64-bit system. A quick estimate is to add up the memory of all GPUs, and multiple by 1.5 ( if you have 5, 8 GB GPU, 58 = 40 * 1.5 = 60. If you have a smaller drive another way would be to add up all GPU memory, then add how much system RAM you have ( consider the above system again, with 8 GB system RAM, so 58 = 40 + 8 = 48 ). Since Windows still lists this in MB instead of GB, you could just start at 40000 and end at 60000.

  1. In some cases service is blocked by the ISP, SkyLink for example, this will have to be taken up with their support.

If after checking the above steps the ERROR still persists please try the following troubleshooting steps for Windows.

If you are using the Windows Desktop application (Cudo Miner GUI)

1. Open up your CudoMiner GUI
2. Go into the jobs tab
3. Restart the failing jobs that you see by clicking the red circles.
- You'll need to scroll up/down to see the full list.
4. Your miner should now start re-trying to mine

If you are using the CudoMiner CLI, did you install the CudoMiner CLI Tools too ?

If you do have the CLI Tools, follow these steps to restart your miner failing jobs :
1. Open a command prompt / terminal on your OS
2. Type or copy paste “cudominercli reset --job-backoffs” into
the command prompt / terminal, and press enter to execute.

3. Your miner should now start re-trying to mine.

If you don’t have the CLI Tools and is on windows based machine, follow these steps to restart your miner failing jobs :

1. Open a command prompt with administrator permission.
2. Type or copy paste the command under this second step into 
   the command prompt / terminal, and press enter to execute after 
   it is copied successfully.
    
   cd "%ProgramData%/Cudo Miner/store/" && del job-backoffs.json && net stop cudominer && net start cudominer

3. Your miner should now start re-trying to mine.

Alternatively, you can go to Your (C:) drive > ProgramData (you may need to make this folder visible) > Cudo Miner > Store > delete job-backoffs.json > restart service.

If you are on CudoOS, the CLI tools are installed automatically, please follow these steps instead :

Run the following command: cudominercli reset --job-backoffs
