Hi @msheikh We are sorry to hear you're facing this issue.
You're right Azure does automatically assign SSL to static web apps in the default domain. However, there can be a few reasons why you might be seeing the ERR_SSL_PROTOCOL_ERROR so here are a few troubleshooting steps you can take:
- Clearing the SSL state in your browser can sometimes resolve this issue
- Clearing your browser cache and cookies
- Some browser extensions can interfere with secure connections. Try disabling them to see if that resolves the issue
- Make sure your browser is up-to-date
- Temporarily disable your Antivirus and Firewall as they can sometimes incorrectly block a secure connection
Hope that helps
