Can anyone help me troubleshoot this? I am trying to get a testnet node running. After syncing for quite a while I get this error:

  • You need to double check your genesis fine is 100% correct. Do not copy paste it, download it. Even one space of difference can be problematic. Aug 26 at 18:42
  • I had changed some values in the config files that solved some other errors I was seeing, but since I do not know enough about how things are setup, I went ahead and started from scratch making sure to download the files as you suggested. Everything is working correctly now. Thanks for the info.

  • Thank you, I think this is because of the genesis file. I will fill it as an answer, please flag it if helpful. Aug 27 at 15:56

This could happen when you genesis file is not matching your peers. Make sure you download the file, without editing. Even a single space of difference will result in a different genesis hash.
