First off, pardon if this was reported or already solved.
I'm trying to set up a local sake APNS server, which comprises nginx
with http/2 config in a docker container plus a silly upstream server
in another container.
The connection is (and must be) http/2 with client cert.
And then I run a command like this:
curl -v \
-d '{"aps":{"alert":"test","sound":"default"}}' \
-H "apns-topic:com.yourcompanyname.yourappname" \
-H "apns-expiration:1" \
-H "apns-priority:10" \
--http2 \
--cert .fake-cert \
https://localhost:2197/3/device/blah-blah-token -k
I get a weird endless retry from curl, one cycle of the retry looks like this:
* Connection state changed (MAX_CONCURRENT_STREAMS == 1234567890)!
* REFUSED_STREAM, retrying a fresh connect
* Connection died, retrying a fresh connect
* Closing connection 988

I don't know why nginx closes the stream, it's weird...
But it's also quite so weird that curl just doesn't give up and tries
again and again and again...
