it seems that you have a service on port 438
Jan 22 15:00:21 cv nginx[27581]: nginx: [emerg] socket() [::]:438 failed (97: Unknown error)

[thawri1]

there is no other service installed.
I tried multiple times for a new server.
I getting servers from serverspace.io

Use this command to kill the process on port 438:
kill $(lsof -t -i:438)

kill $(lsof -t -i:438)
