Why am I getting HTTP/2 Stream 0?

The "HTTP/2 stream 0" error has been reported frequently, but I have yet to find a consistent way to reproduce it. The situation is further complicated by the fact that most users are behind proxy servers.

It's unclear whether this is a bug in the FLClient library itself or a server-side issue. Based on your situation, here are some general recommendations:

• Remove the Content-Length header: Try sending your request without this header.

• Evaluate proxy servers: Determine if the error is related to the proxy servers you're using. If so, consider switching to higher-quality proxies.

• Check for blocking: If the issue persists over time, it could be that the request is being blocked by services like Akamai.

• Force HTTP/1.1: Some sites have faulty implementations of HTTP/2, so forcing HTTP/1.1 might resolve the issue.

Finding a reliable way to reproduce the error would help us address it more effectively or at least work around it.
