Re: curl: (16) Error in the HTTP2 framing layer

The curl problem is intermittent. So I can not debug the problem easily.

I can connect the server using a browser. But there is no way I can be
sure the connection via the browser always work or not.

So there is not anything that I can do easily to mitigate this problem?
