Tls default domain for tcp router with no SNI

Hi!

any idea how a dynamically configured router can set the correct certificate with rule=HostSNI(*)
clients support no SNI, so this router takes over the entire endpoint.

traefik.tcp.routers.thingy.tls.domains.main=mydomain seems to have no effect

Except that it took me way longer to figure out what the problem was, I have the same question over here: Cant get the HTTP out of træfik

Unfortunately no solution yet.
