E[2021-12-03|15:47:05.244] Error dialing seed module=p2p err="auth failure: secret conn failed: read tcp 172.30.30.243:58364->18.138.237.114:26656: i/o timeout" seed=9942597c62826d0c25b65203cde1574470653e6e@18.138.237.114:26656
E[2021-12-03|15:47:05.244] Couldn't connect to any seeds module=p2p

I setup the full node according to the document, the program always reports the above error.

This error occurred because of network connectivity issues with seed, you could try more seed in your config.toml:
