Hello, After submitting onboarding form for Live Caller ID Lookup feature, we received rejection response that our OHTTP gateway doesn't support HTTP/2. We have run provided command openssl s_client -alpn h2 -connect with our domain several times from different machines and environments, and our results consistently confirm that HTTP/2 is indeed supported by our OHTTP gateway. The output clearly shows ALPN protocol: h2, indicating successful HTTP/2 negotiation. Here is the log chunk from the command-line response: No client certificate CA names sent Peer signing digest: SHA256 Peer signature type: RSA-PSS Server Temp Key: X25519, 253 bits --- SSL handshake has read 4393 bytes and written 406 bytes Verification: OK --- New, TLSv1.3, Cipher is TLS_AES_128_GCM_SHA256 Server public key is 2048 bit This TLS version forbids renegotiation. Compression: NONE Expansion: NONE ALPN protocol: h2 Early data was not sent Verify return code: 0 (ok) --- DONE We have also tried different 3rd-party services to check the HTTP/2 support and they also confirmed that HTTP/2 is supported. Is it possible to provide additional details on the specific criteria or test conditions that led to its non-approval? I'm happy to provide any further diagnostic information or engage in more detailed technical discussion.
