Posted on by vsomireddy 40

I am trying to call Internal IBM Integration Bus(IIB) service from CRM Plugins, but it is not working, it is throwing following exception. If i try to call same service from .Net application, it works fine. can you pls let me know what could be the problem? Service should be exposed to internet always to call from CRM Online Plugins?

    If you are running online make sure that the address you are trying to connect to is accessible from the internet. Unless you own the test.com domain, this is very likely to be an internal address not exposed to the internet.

    Hi,

    The issue may be due to any of the following reasons.

    1. Check the credentials.

    2. Windows firewall might be ON.

    3. Configure web.config

    4. Enable HTTPS host header

    Most likely the firewall issue.

    CRM server can't communicate with the server hosted the web service.

    Try few things to identify the issue:

    1.Try to off firewall? (Quick and dirty way)

    2.Try to ping/telnet the server (making sure the DNS is correct, port is open)

    3.Try portquery (one of the favourite tool to test the firewall port)

    Once you know the issue you can find the solution.

    Hi,

    Are you on Dynamics 365 Online or on-premise? If Online, then what URL are you using for the endpoint? It looks like you are pointing to a local server that is not accessible to the plugin.

    Please also note that plugins cannot call a web service using an IP address. It should be a DNS name (fully qualified name). You also need to check the Trust if it is full or partial based on if it is on-premise / IFD installation or a CRM Online one.

    Read more about the plugin isolation considerations here:

    If you found my response helpful, please mark "yes" to confirm it helped you.

    Hi,

     crm plugins are running on the CRM server (and, it seems, you are using CRM online, so your plugins are running on the MS servers). If the plugin is trying to connect to a web service, that web service has to be accessible from the CRM server. From the error message, it seems that it's not the case:

    "The remote name could not be resolved: 'esb1.stdev.test.com'"
