I have built an on-prem CRM 2016 environment, one CRM server and one SQL 2014 server for SSRS.  The installation went well and everything (claims/IFD) seems to be working as expected with the exception of reporting.  Whether I attempt to run/edit an existing report or create new, I receive error:

Error occurred while fetching the list of data extensions installed on the report server.

I receive two errors in Application event log on CRM server, 19968 and 1309.  Details of 19968 are:

Web service request ListExtensions to Report Server http://sqlserver/reportserver_instance/reportservice2010.asmx failed.  Error: The value of the property 'proxyaddress' cannot be parsed.  The error is: Invalid URI: The URI is empty. (C:\Program Files\Microsoft Dynamics CRM\CRMWeb\web.config line 387)

I can browse to the report server url from the crm server, login and see the reports listed.  I can access the reportservice2010.asmx page from crm server.  I've tried reinstalling report extensions on SQL, rebooted both servers, tried to add "enable="false"" in web.config defaultproxy section, just in case but no luck. 

It certainly seems like crm server can't see report server but I'm not sure why.  There is nothing in the SSRS log file or event logs that I can find.

Any help/direction would be appreciated.

I finally figured this out, sort of...

As suggested in my first post, the CRMWeb\web.config contained this entry at the bottom under system.net:

<defaultProxy>

     <proxy bypassonlocal="Unspecified" proxyaddress="" />

   </defaultProxy>

I have no idea why this was in the config file but it was not in my 2015 prod web.config file.  So I removed it and rebooted the server and the problem seems to be gone.  

It would seem this entry was causing CRM to look for a proxy server (which we don't have) that was null and then bombing out.  

I hope this helps someone...
