Subdomain re-render on app root

[WilliamConsumer]

Summary

Project structure: The project needs to work with dynamic subdomains, so the route could be something like www.domain1.site.com.

I’ve created a default Next.js structure and started handling the subdomain path in middleware, and it worked fine.

Problem: With this structure, if I check the template.tsx or layout.tsx, it is being called twice. If I remove the subdomain from the URL, it is only called once.

How can I fix this?
