Error setting up the RPC node connection: The public IP address of the validator cannot determine

As a Solana developer, you are probably no stranger to set up a remote server for tests and development. A common problem that can occur when using Hetzner servers is the connection to the RPC node. In this article we will not determine with the error “Do not determine the public IP address of the validator” and examine potential solutions.

The problem: The public IP address of the validator cannot determine

The error message indicates that the Solana -RPC node connection is coordinated due to the inability to maintain the public IP address of the validator. This is a common problem when using a rented Hetzner server, as it can be difficult to receive the public IP address of your server directly.

Step by step error correction

To solve this problem, follow these steps:

Check your server configuration : Make sure that your Solana server is set up via the required firewall rules to enable incoming connections from other machines.

Check the network connectivity : Check the network connection of your server by IP AdDR orDig +Short 8.8.8.8. Execute to determine whether the router works correctly.




 Check the IP address assignment : Make sure that your Hetzner server will be assigned via a public IP address via your account settings or DNS configurations.

V. Use the "Curl" command: Try the "Curl" command to get the public IP address of the validator:curl -i localhost: 8555

Check the RPC node configuration : Check your Solana -RPC node configuration file (solana.config.json) for typing errors or incorrect settings that can prevent the connection.




 Check the firewall rules 

: Make sure that the firewall rules do not block the incoming connections from other machines.


 Potential solutions 

If none of these steps fix the problem, you should take some potential solutions into account here:


Contact your Hetzner Server Administrator via IP address problems or configuration problems.

Try to use another RPC node connection method likehttp: // localhost: 8555instead of 'curl.

Make sure that the Solana client is configured correctly and does not cause any conflicts with the RPC node.

Diploma

In summary, the public IP address of the validator can be a challenging problem if an RPC node is set up on a rented Hetzner server. If you follow these steps and have instructions for troubleshooting, you should be able to solve the problem and establish a successful connection to your Solana -RPC node. If the problem continues to exist, do not hesitate to contact Hetzner’s support team or to receive further support from the Solana community.
