Error while parsing rule Host()

I also made a ticket in traefik’s community but they are not very responsive.

i notice that it is very strict on using the werid quote ``
syncCatalog can detect the rules but regular consul connect cannot detect the rules

traefik.enable=true,traefik.http.routers.static.rule=Host( webservice.domain ) && (PathPrefix( /siteone )

is there a way to escape the ` quote ?

basically it comes out as

traefik.http.routers.static.rule=Host() && (PathPrefix()

I also notice even though it shows an error, the pathprefix does work

note that i am using kubernetes environment.
