Traefik don't work with OpenLiteSpeed

[HuhuLaColle]

Hello, I have a problem with traefik that I would like to connect to an openlitespeed container, the litespeed container works fine, if I go to localhost:81 I receive the response from openlitespeed, but admin.localhost returns a "Gateway Timeout" from Traefik, I do not understand what I missed, the domain in openlitespeed is registered in localhost, it may have a relationship?
