What is happening: 1) Works correctly only if traefik does not manage let's encrypt certificates itself (otherwise it does not transmit any request whose pathPrefix begins with ".well-known/acme . Finally looping back on this. You can define TLS termination separately on each router, configure TLS passthrough, use the new CertResolver to benefit from .

OnDemand option (with HTTP challenge) This configuration allows generating a Let's Encrypt certificate (thanks to HTTP-01 challenge) during the first HTTPS request on a new domain. To enforce mTLS in Traefik Proxy, the first thing you do is declare a TLS Option (in this example, require-mtls) forcing verification and pointing to the root CA of your choice. Leveraging the serversTransport configuration, you can define the list of trusted certificate authorities, a custom server name, and, if mTLS is required, what certificate it should present to the service. I've observed this as once the issue is replicated in one browser tab I can go to other browser tabs (under the same instance of Chrome) and try to make requests to the same domain and they will all sit there and spin.
