I am trying to use the HMAC function in a swift package but it does not work it only works in standard view controller style packages. let hash = HMAC<Insecure.SHA1>.authenticationCode(for: counterData, using: SymmetricKey(data: secret))

I can connect via terminal but when i send request i get Connection state changed (MAX_CONCURRENT_STREAMS == 1)! We are completely uploaded and fine TLSv1.2 (IN), TLS alert, close notify (256): Empty reply from server Connection #0 to host api.sandbox.push.apple.com left intact curl: (52) Empty reply from server and it times out. i can connect openssl s_client -connect api.sandbox.push.apple.com:2197 CONNECTED(00000006) but it randomly stopped working I am using a valid JWT token.
