Remote Thing is not binding after successful authentication. It gives "Bind request failed" error

[Aruna]

We are using .Net SDK for edge implementation. Sometimes it gives "Bind request failed" error and connection doesn't happen but sometime client gets connected to server still the same error is thrown. Not able to find the exact root cause for the issue.

Here is the SDK logs.

What versions are you using, for both SDK and the platform?

Is there anything in the application log on the ThingWorx platform side?

[Aruna]

.net SDK version - 5.7.6.3407

server version - ThingWorx 8.2.1-b140

I apologize for the late response, for some reason I did not get notifications about this. Do you have a firewall enabled, perhaps? Could you please share your configuration too?
