Manual backup is stuck at 0% in SolusVM 2

Symptoms 

• Manual backup is stuck at 0% in SolusVM 2

• While pinging the Management Node hostname (example.com) that has the IP 203.0.113.2 it occurred that actually, it is resolved via another IP address:

  # ping example.com
  PING example.com (203.0.113.3) 56(84) bytes of data.
  ...

• The server has been purchased from the Cloudflare company

Cause

Cloudflare redirected traffic to their servers but the connection to port 5671 was prohibited. This port is required for the rabbitmq service - it is responsible for the tasks in SolusVM 2.

Resolution

1. Log in to the Compute Resource via SSH.

2. Change the IP in the configuration file on the CR /etc/solus/agent.json so that it has the correct IP 203.0.113.2:

   # cat /etc/solus/agent.json | grep "api_host"
   "api_host": "203.0.113.2",

Otherwise, contact Cloudflare to open port 5671 or deactivate the proxy mode.
