Allow port 8443 in the security group or firewall

The WP Panel is accessed by default via8443port. If the software displays „Cannot connect to port 8443 from your computer“, the most common cause is that the cloud server security group has not allowed it.

Allow the security group port

1. Log in to the cloud provider console and open the VPS details page.
2. Locate „Security Group“, „Firewall“, or „Inbound Rules“.
3. Add a TCP inbound rule and enter the port8443, and set the source according to your security requirements.
4. Save the rule and wait for it to take effect.

Return to the assistant to check

After allowing it, return to the assistant and click „Check port 8443“. Once it shows „Accessible“, open the panel address saved at the end of installation in your browser.

If it is still unreachable after the security group has been allowed, check the server's internal firewall. Entry points and screenshots for different cloud providers will continue to be added.
