Problem Failed to register agent with the server. Waiting to retry ...

I have a problem with the registration of an agent installed on the datastore server.

The error message below. registerAgentProcess (): No response data Failed to register agent with the server. Waiting to retry ...

I've already done the installation twice and it's always the same. I launched the dubug for the agent:

agent.config - registerAgentProcess (): No response data ERR 4224.2592 20210309: 111139 agent.config - initAgentConfig (): Failed to register agent with the server. Waiting to retry ...

Please help.
