 Hi,

I am not sure if this is the correct area to post this, but I have an issue with getting an API request through my Checkpoint 1490 appliance. It works normally when not connected through the checkpoint appliance. I do not see any indication in the logs as to what the issue can be. Can someone please me guidance on how I can troubleshoot this issue.

Thanks,

William

What precisely is making the API call?
What is it making it to?
What software build?
