Substrate node template (version polkadot-v0.9.26) could not find any peers including itself (as I understood) and does not produce any blocks. I did not add any lines of code. Logs:

What could cause such problem? I tried to run it several days ago and it worked properly, but I don't know how to trace what has changed.

I'm using macos 12.5 (intel version), firewall is off. I also have installed zerotier with several networks connected, but it wasn't a problem earlier.

  • I don't have any other peers Aug 6, 2022 at 15:04
  • What's your boot command? Aug 6, 2022 at 15:57
  • Just ./node-template. I forgot about --dev flag, thanks for the tip! Aug 7, 2022 at 9:37
  • Iā€™m voting to close this question because its misleading, the solution is a simple mistake

Adding --dev flag to the boot command helped. Turned out this problem has no relation to network error.
