I am unable to connect to APNs sandbox push endpoint from our backend servers. It works fine when hitting the request from my local machine but it fails from the infra servers. Here are the complete curl details.

Endpoint: https://api.sandbox.push.apple.com:443 CURL request and response:

curl -v https://api.sandbox.push.apple.com:443

Trying 17.188.168.149:443... Connected to api.sandbox.push.apple.com (17.188.168.149) port 443 ALPN: curl offers h2,http/1.1 Cipher selection: ALL:!EXPORT:!EXPORT40:!EXPORT56:!aNULL:!LOW:!RC4:@STRENGTH TLSv1.2 (OUT), TLS handshake, Client hello (1): CAfile: /etc/pki/tls/certs/ca-bundle.crt CApath: none OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to api.sandbox.push.apple.com:443 Closing connection curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to api.sandbox.push.apple.com:443

There are no issues with Production endpoint. Can someone help? Verified all certificates. Everything worked fine until 29th July but started failing since 30th July

Here is the PCAP file. Additionally, Here is the outbound public IP : 3.251.214.255

We are not able to see what the cause of the issue is from the pcap file you have attached.

We would like to see a raw pcap (as opposed to human readable format) that includes TLS details.

That would be hard to attach here. You can possibly post it online and reply with a link. But if you would rather not do that on a public forum, please open a support request at https://developer.apple.com/contact/request/code-level-support/ and reference this forum thread in the "Did someone from Apple ask you to submit ..." section, and in your message let us know the link to download the raw pcap file. Please make sure that you turn on as verbose as possible options so we get all the info we need.
