Alternative HTTPS
What is Port 8444?
Port 8444 is used as an additional alternative HTTPS port when both 443 and 8443 are occupied. It's commonly found in environments running multiple HTTPS services. Some specific tools use it — Chia blockchain's daemon uses port 8444 for peer connections. Various application servers and custom deployments use this port for TLS-encrypted web interfaces. In Docker and container environments, port 8444 is mapped for additional secure web services.
Common Uses
- Chia blockchain peer connections
- Additional HTTPS service endpoint
- Container HTTPS port mapping
- Custom TLS web applications
