Server callWithGET occasionally returns empty object and server status 0

[Lunacy Audio]

I think I'm doing pretty standard server stuff in my HISE script, but Server.callWithGET seems a tiny bit unreliable when I try to activate user licenses and will sometimes return empty objects with the server status 0.

I've tried the same call to my Woocommerce server on Postman without any issues, so it's directly related to HISE. Anyone have any thoughts on this? I'm wondering if there's a hidden timeout or something else in my HISE script could be creating a conflict. Thanks!
