asp.net mvc publish not open in clients

Question

I have two asp.net mvc projects on my server. (iis 7 and win server 2012R2).

Both (app1 port:80 & app2 port:83) work and open on server. But app2 with port:83 open only on server and client can not open app2 with link http://IPserver:83

Edge => Error Code: INET_E_RESOURCE_NOT_FOUND

Chrome => ERR_CONNECTION_TIMED_OUT

Is there a config on IIS?

Answer 1

Per the comments, summarizing the solution:

1. Both app1:80 and app2:83 are working if connecting from the server itself (locally).
2. However, on a remote client, app1:80 works, but app2:83 does not work.

The recommendation was that there was likely a configuration issue with the network (or a firewall/port manager/port configuration on the server itself) that is blocking port 83 since it is not a standard port like port 80 is.

One way to test this is to shut down app1 , reconfig app2 to port 80 , and see if the remote clients can connect to app2 on port 80 .
