In this article, we will guide you to solve steps and provide solutions to solve this error.
Understand the error
The “No Source of Block Source Available” usually occurs when the bitcoin-QT portfolio cannot find a valid block source for blockchain ethereum. This can happen for several reasons:
1.
- UPNP Port Conflicts : Bitcoin-QT portfolio can be blocked by firewall gates or operating systems due to UPNP (Plug and Play) activated on a non-standard port.
Steps to troubleshoot
Follow the following steps to solve the “without a block source” error:
Step 1: Check your proxy settings
- Make sure your proxy server is properly configured.
- Try to completely deactivate the proxy server and see if you can manually connect to the Ethereum network.
Step 2: Test with another proxy or port
Try using another proxy server or a non -standard port (for example, 8080) to see if it solves the problem.
Step 3: Activate the upnp on the router
- Check the router parameters and activate the UPNP (Plug and Universal Game).
- Check that the UPNP protocol is activated on the desired port (usually 80 for the HTTP or TCP 80 port).
Step 4: Reboot Bitcoin-QT wallet
- Close the Bitcoin-QT portfolio and restart it.
- Try to manually connect to the Ethereum network.
Step 5: Update your operating system and software on the portfolio
Make sure your operating system and wallet software are up to date, as newer versions can solve Ethereum compatibility problems.
