Hi Sharada, First, can you try calling this function on your test server:

var appVersion = eslClient.SystemService.GetApplicationVersion();

This is the most basic function we suggest to use testing connection with OneSpan Sign, and if this works, it means your connection (proxy or tls related issue) with OSS is fine. And if this call doesn't success, per this thread, can you try switch your test server to .Net 4.6 and then let's see whether the problem remains. Hope this could help! Duo

How about the GetApplicationVersion function, can you receive it? And were you receiving the same null pointer error? Because sandbox env was updated to 11.20 this morning with some connection delay, so can you try it again? Duo

Hi Sharada, Few more questions, #1. are you using proxy configuration on your Test Server and corresponding setting with your code with SDK? #2. can you use some traffic monitoring tool like fiddler to track your connection with OneSpan Sign to see whether your request was reached out to OSS server?

So if you use the same eslClient object and create a package, does it make any difference? Duo

If I run locally on the test server , I get the version number, but I call from outside the TEST server , I still get the object reference error.
