Hello Tahoé ETHEVE - BIMer Services,

Welcome to microsoft Q&A, Thankyou for posting your query here.

Ensure that the web server is running and configured correctly to handle HTTPS requests.

Check if there are configuration errors with the SSL/TLS setup.

If your VM is under heavy load, this might cause the web server to respond with a 503 Error.

Check the network security groups and firewall settings to ensure that the traffic on port 443 (HTTPS) is allowed through to your VM.

A backend service failure can often result in a 503 Error if your application relies on it for completing requests.
