This wont be relevant until there is Service Fabric provider for V2(apologies I only spotted this today)
With traefik v2 and tls pass through configured on. In service fabric if an ip address and not a host name is used for our nodes, a tls certificate validation failure will occur on the host name.
1 way to get around this would be to have a local DNS service use a specific host name.
In a typical microservices deployment where the destination server will invariably differ what strategies are there for this situation. Tls pass through is desirable as it obviously stops MITM attacks.
