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&nbsp;  
  
Here some commands I used to register and errors:  
  
Via HTTPS

```auto
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...
Failed to register pmm-agent on PMM Server: Post "https://kalh.ddns.net:8443/v1/management/Node/Register": dial tcp 116.109.37.80:8443: connect: connection refused.

```

Via HTTP:

```auto
pmm-admin config --server-insecure-tls --server-url=http://admin:Pa$$word@abc.ddns.net:8080
Warning: PMM Server requires TLS communications with client.
Checking local pmm-agent status...

We are sorry to be unable to perform the method POST to non-script at this time.&lt;P&gt;
If you would like to see this capability in future
releases, send the method which failed, why you
would like to have it, and the server version DrayWeb/0.0.2
to &lt;ADDRESS&gt;http://www.draytek.com/&lt;/ADDRESS&gt;&lt;P&gt;
&lt;/body&gt;
&lt;/html&gt;

&lt;strong&gt;The requested URL was not found on this server.&lt;/strong&gt;&lt;/font&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;/table&gt;
&lt;/body&gt;
&lt;/html&gt;
.
Please check pmm-managed logs.

```

Please tell me what should I do?  
Thanks and best regards

Never mind!  
  
I didn’t open an outgoing port on the MySQL server. How stupid I am
