Still happening unfortunately - below are the console outputs from the
Ubuntu 20.04 amd64 machines hosted on Vultr across Paris, New York and
Sydney - all instances only had IPv4 connectivity. I get the same outcome
with wget or curl.

I captured and decrypted a session with Wireshark, and half way through the
download the client receives a HTTP/2 RST_STREAM command with error code 2
(INTERNAL_ERROR).

Roy: is the nginx grpc module being used on your webserver at all? When
googling for this, I see a lot of forum posts related to that module, and
some recent commits to the nginx repo related to that module.
http://hg.nginx.org/nginx/rev/716eddd74bc2
http://hg.nginx.org/nginx/rev/2096b21fcd10
http://hg.nginx.org/nginx/rev/2e61e4b6bcd9
http://hg.nginx.org/nginx/rev/fd6dcc6f8a49
http://hg.nginx.org/nginx/rev/29b2dc731503

Anyone have any ideas how I can troubleshoot further?
