Gravity Ledger Node in devnet cannot dial its peers

[sapranidi]

I am trying to deploy a Gravity Ledger node following the Docker guide using a Digital Ocean VM. As seen in the logs below, the node attempts to connect with its peers via tcp and fails:

E[2021-02-23|22:32:50.308] dialing failed (attempts: 1): dial tcp 161.35.207.224:26656: connect: connection refused module=pex addr=c22e04514ce4ae0feb3480d03593d34e4713c86d@161.35.207.224:26656 E[2021-02-23|22:32:50.812] Error dialing peer module=p2p err="dial tcp 161.35.207.224:26656: connect: connection refused" E[2021-02-23|22:32:51.296] dialing failed (attempts: 1): dial tcp 164.90.184.213:26656: i/o timeout module=pex addr=32a091dfea2b4191d710d2609ca21a8abfe585ac@164.90.184.213:26656 E[2021-02-23|22:32:51.296] dialing failed (attempts: 1): dial tcp 164.90.185.82:26656: i/o timeout module=pex addr=34f38d98e78ed7965a56399998d9c1dccba24fe1@164.90.185.82:26656 E[2021-02-23|22:32:51.297] dialing failed (attempts: 1): dial tcp 104.248.255.124:26656: i/o timeout module=pex addr=2a0d75cc7833ad4780a1035b633c5bf4ef94ea4c@104.248.255.124:26656 E[2021-02-23|22:32:53.372] Error dialing peer module=p2p err="dial tcp 164.90.184.213:26656: i/o timeout" E[2021-02-23|22:32:54.220] Error dialing peer module=p2p err="dial tcp 104.248.255.124:26656: i/o timeout"

My initial guesses:

1. The list of peer nodes in devnet is not up to date.
2. The guide needs updating.

Please examine this issue and let me know how to resolve it, thanks!
