Workers on a second level subdomain

Hello,

I was trying to deploy my worker with wrangler to a second level subdomain, e.g.: app.staging-abc.example.com. And it wasn’t working at all, I was constantly getting HTTP 522 error while wrangler dev was working correctly on my local.
When I tried to deploy the same worked to the first level subdomain, it magically worked.

Is there a way to deploy workers to a second-level subdomain? Where can I find it in the documentation?

Thank you,
Alex

The first problem that comes to mind is SSL. Did Wrangler push it, but then it didn’t work?

Thanks sdayman, you nailed it. I was relying on universal SSL, didn’t check its manual to understand the limitations. Though Workers/wrangler didn’t show any warnings or relevant errors.
