Cannot port forward to Spark outside Local Network

This could be the socket close issue that I saw when porting the library

I thought I had fixed it by introducing a small delay, which made it more stable. (Naturally, that’s just a bandaid until we can uncover the real cause of the problem.) Could you please confirm again that this is working fine via your local net?

EDIT: ah, I saw now you said it times out locally too.

Thanks!
