Matrix delegation not working

📣 Notification Service(s) Impacted
Matrix

🐞 Describe the bug
My matrix server is configured with delegation and I cannot create a notification when using the root domain.

💡 Screenshots and Logs
Using root domain with following delegation setting: {"m.server": "matrix.<domain>:443"}

💻 Your System Details:

• OS: Arch Linux
• Python Version: 3.11.7
• apprise: 1.7.2

🔮 Additional context
I can live with the subdomain in the URL but finding the problem was annoying and I think this should be supported because it is part of the official matrix specification.
