Hi!
I'm planning to set up a custom domain name for my Event Grid Namespace MQTT endpoint.
I'm trying to set it up using a placeholder self-signed cert and I'm getting the following error:
Custom domain addition failed with error: "No subject names in certificate wildcard-tls-cert match the custom domain mqtt.example.com"
The certificate has a subject set to: *.example.com
I was scanning through the documentation of EGN and couldn't find if it supports wildcard certificates. Anyone can answer this question?
BR, PM

@PM Thanks for reaching out. Wildcard certificates are not currently supported for custom domains in Event Grid. We will pass this feedback to our documentation team to add a note regarding this limitation.
do let me know incase of further queries, I would be happy to assist you.
