Azure error logging

"502, 503 or another 5xx error"

Quick fix

It is simple deploying apps for the Azure App Service, but sometimes you end up with a sad (and rather cryptic) 502, 503 or another 5xx error when starting the app, when things don't go as planned.
These problems are tricky to debug because the app has not started yet and therefore cannot display a useful error message itself. The server will then simply display a generic and hard to understand error page.

VPN client error: Error 912

"error 912"

Quick fix

The connection was prevented due to a policy configured on your RAS/VPN server. (Error 812) This error occurs if the RADIUS server you used to authenticate the VPN client has incorrect settings or the Azure Gateway cannot reach the Radius server.

Hint:

Make sure that the RADIUS server is configured correctly. For more information, see Integrating RADIUS Authentication with the Azure Multi-Factor Authentication Server.
