# Common Issues ``` RuntimeError: DHTNode bootstrap failed: none of the initial_peers responded to a ping. ``` This error results when a connecting node can't connect to a bootnode. This can be the result of an incorrect bootnode address, or an authorizer error, such as a proof of stake failure, or signature validation failure. Make sure the `.env` file has the correct bootnodes, or the server is retrieving the correct bootnodes another way. If the subnet is relying on the `.env` file, any changes to it must be built with `pip install .` for those changes to take effect. *** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
