403 error from app requesting report rendering

Question

hi i'm geting particulars on the calling app but a peer of mine trying to render my report from his app got the following error. i reached out to him to determine if he entered the ssrs report directory correctly but if the community can offer insight on what else this might be pls help. when i see ssrs refusing something, i think first of those server settings you often have to enable on the engine server in order for it to take requests from outside of the server itself...

Hi,

From the error message, I assume that the report server refused the request from the app.

I think the issue is more likely to be related with the development of the app.

I did some research locally.

Someone said that this error occurred when your firewall blocking the connection or process that is hosting the service is not listening on that port.

Refer these links to see if it can be useful:
