LTI Proxy Error

[joseph3]

My University's security team appears to have made some firewall changes that impact my  development server.  Any applications that are supposed to load in a Canvas frame fail with a proxy error.  I can get them to work from my production server or localhost running off of my desktop, but not the development environment.  I was told that I need to make a request to security with source, destination, and port information.  I would assume that the source is the URL for our canvas test instance, and the destination is my development server address. Does anyone know of a specific port that I need to request?

LTI will just use the same HTTP/S port as your server, this would normally be 443 for https.  HTH.

Perhaps an issue with the referrer policy. I know that Canvas by default uses 

strict-origin-when-cross-origin

and perhaps your proxy is set the same way.

Hey! Dealing with firewall changes is frustrating! From my experience, if you're trying to access your development server from within a Canvas frame, it might be worth checking if the firewall is blocking certain ports. As for residential proxies, they could help bypass restrictions, but it's essential to ensure they're allowed by your university's security policies. Good luck sorting it out!
