@Anshuman Srivastava ,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I am afraid your verbatim is not clear and I am unable to understand what your requirement is.

Per your verbatim,

You have a QA Environment where the Wildcard Listener is working, while the same is not working in Dev Environment

Is this correct?

Or QA Environment has Basic listener while Dev Environment is having a Wildcard Listener.

Can you please elaborate where you face the issue?

Is your intention is to have 2 Listeners?

One with subdomain1 and another with subdomain2

Or your intention is to have 1 Listener with multiple domains?

i.e., a single Listener with subdomain1 and subdomain2

Please elaborate your set up elaborately.

Cheers,

Kapil

Hello Anshuman Srivastava,

Welcome to the Microsoft Q&A and thank you for posting your questions here.

I understand that you're having issue with application gateway not able to route properly.

Among many things you can check are Listener Configuration, DNS Configuration and Routing Rules.

Most of all, v2 SKU can affect how requests are routed so, make sure that multi-site listeners are processed before basic listeners unless rule priority is defined - https://learn.microsoft.com/en-us/azure/application-gateway/configuration-listeners

Also, you can use tools like Azure Network Watcher to diagnose and troubleshoot network issues and if you have logs enable, review and let see more error or information that you get.

I hope this is helpful! Do not hesitate to let me know if you have any other questions.
