The 'Receive error: 10053 connection was aborted by the software in your host machine' error occurs when Folding@home cannot establish a stable connection with the client's server. This issue affects users who are trying to contribute their unused GPU computing power to help fight against COVID-19.

This error can be frustrating as it prevents you from contributing to the Folding@home project and may cause delays in your progress. However, don't worry, as we will guide you through a step-by-step process to resolve this issue.

🔍 Why This Happens

  • The primary reason for this error is that the client's server requires a specific version of CUDA (NVIDIA's API) to be installed on the host machine. If the CUDA library is not found, or if it is outdated, Folding@home will not be able to establish a connection with its server.
  • Another possible cause could be that the system's firewall settings are blocking the communication between the client and the server. Additionally, if there are any issues with the host machine's network connectivity or the GPU itself, it may also lead to this error.

🚀 How to Resolve This Issue

Update CUDA Library

  1. Step 1: Step 1: Download the latest version of NVIDIA's CUDA toolkit from the official website.
  2. Step 2: Step 2: Install the downloaded CUDA toolkit on your system. Make sure to select the correct architecture (32-bit or 64-bit) and version that matches your host machine's specifications.
  3. Step 3: Step 3: Restart Folding@home Client after installation is complete.

Disable Firewall Settings

  1. Step 1: Step 1: Open the Windows Defender Firewall settings by searching for 'Windows Defender Firewall' in your system's search bar.
  2. Step 2: Step 2: Click on the 'Allow an app or feature through Windows Defender Firewall' option and select Folding@home Client from the list of allowed applications. This will allow the client to communicate with its server without being blocked by the firewall.
  3. Step 3: Step 3: Restart Folding@home Client after updating the firewall settings.
