Hello Contabo Support Team,

I have a VPS with IP address 95.000.000.00. I have installed CyberPanel on this VPS.

My WordPress website is hosted on this VPS. I need to send emails through an external SMTP server (Plesk) located at IP: 91.000.000.000 on port 465.

However, when I try to connect from my VPS to this external SMTP server, I get a “Connection timed out” error.

Here is the strange part:

  • From my local home computer, I can successfully connect to 91.000.000.000 on port 465 (Test-NetConnection shows TcpTestSucceeded: True)
  • But from my Contabo VPS (95.000.000.00), the connection always times out

I have already checked my CyberPanel firewall - all outgoing ports are open. The issue seems to be at the network/hypervisor level.

My VPS details:

  • IP: 95.000.000.00
  • Destination SMTP server IP: 91.000.000.000
  • Ports I need: 25, 465, 587

Can you please check and unblock outgoing SMTP ports (25, 465, 587) from my VPS to external servers? My WordPress site needs this to send emails properly.

Thank you for your support.
