No Domain found in rule HostRegexp

Traefik Traefik v2
1

I am trying to allow 2 different paths, and a range of incoming set path variables, to be accepted by the HostRegex rule for my Kubernetes-IngressRoute. However no matter what I do, I am always presented with the following error, "No domain found in rule HostRegexp({host:.+\.X\.Y.(path1|path2)\.com\.au}) the TLS options applied for this router will depend on the hostSNI of each request".

Any Idea on what I might be doing incorrectly? Any help would be appreciated, cheers.

Hi @nickyg,
Thanks for your interest in Traefik.

Could you provide your Traefik, and your ingressRoute configurations? So I can try to reproduce and understand what's going on :slight_smile:

Thanks,
