Can't register the client

Percona Monitoring and Management (PMM) PMM 2.x
1

Hey guys,

I tried to install PMM2 with these configs:
- PMM server: On my MacOS (w/ Docker)
- PMM Client: My MySQL server (CentOS)
- Using DDNS (No-IP) to connect between client and server 

Here some commands I used to register and errors:

Via HTTPS

pmm-admin config --server-insecure-tls --server-url=https://admin:Pa$$word@abc.ddns.net:8443 

Checking local pmm-agent status...
pmm-agent is running.
Registering pmm-agent on PMM Server...

Via HTTP:

pmm-admin config --server-insecure-tls --server-url=http://admin:Pa$$word@abc.ddns.net:8080

Never mind!

I didn’t open an outgoing port on the MySQL server. How stupid I am
