As shown above, the application relies on Traefik Proxy-generated self-signed certificates the output specifies CN=TRAEFIK DEFAULT CERT. From inside of a Docker container, how do I connect to the localhost of the machine? The host system somehow transforms the HTTP/3 traffic and forwards it to the VMs as HTTP/1 or HTTP/2. Traefik configuration is following From now on, Traefik Proxy is fully equipped to generate certificates for you. Would you mind updating the config by using TCP entrypoint for the TCP router ? When working with manual certificates, you, as the operator, are also responsible for renewing and updating them when they expire. Sometimes, especially when deploying following a Zero Trust security model, you want Traefik Proxy to verify that clients accessing the services are authorized beforehand, instead of having them authorized by default.
