c# - WCF: "Failed to open System.ServiceModel.Channels.ClientReliableDuplexSessionChannel" -


I currently have a WCF service with a callback agreement (duplex), and when I use that application It uses its computer everything works fine, but when I try it from a different computer, it does not connect.

Once these problems have occurred I started switching to callback using this wsDualHttpBinding because when I wsHttpBinding everything is fine has worked.

Why is not the web service accepting requests from other computers? Is it necessary to modify some hosting settings?

Regarding logs, I am getting this:

within the allotted time of open operation 00:01:00 Not completed Time may be a part of a long term expiration allocated for this operation

Failed to open System.ServiceModel.Channels.ClientReliableDuplexSessionChannel

Error System.ServiceModel.Channels. ClientReliableDuplexSessionChannel

     Now I switch from  wsDualHttpBinding  to  NetTcpBinding  And for some reason, everything is working fine 
     
     I have used to help in establishing hosting on IIS, and thanks to the callback, everything works. Used to be.

    I now switch from wsDualHttpBinding to NetTcpBinding And for some reason, everything is working fine.
