OpenZiti Controller TLS Handshake Failure - "not handler for requested protocols [h2 http/1.1]"

Environment: - OpenZiti v1.6.12 - Ubuntu 24.04 LTS - Controller running on port 6262 Problem: Edge API TLS listener rejecting standard HTTP/1.1 connections. Error: "not handler for requested protocols [h2 http/1.1]" Details: - Certificate chain is valid (generated with proper EKU: TLS Web Server Authentication) - Subject Alternative Names correct (localhost, internal IPs, siti.myrepublic.net.id) - Key Usage extensions correct - But TLS handshake fails with EOF errors Curl test result: curl -k https://127.0.0.1:6262/version → error:0A000438:SSL routines::tlsv1 alert internal error Controller logs: {"_context":"tls:0.0.0.0:6262","error":"not handler for requested protocols [h2 http/1.1]"...} Question: How to configure OpenZiti controller edge API to accept standard HTTPS/HTTP1.1 connections? Or is there a different protocol/configuration required?

Hi @andhika.ridwan, I'm sorry but I don't understand what you've done here and what you're trying to do.

If you're generating your own certificate chain, you really need to understand that process fully. There are discourse posts that have discussed this in the past. See this thread from just last month, it might help you?

Other than that, I'm not exactly sure how to help with what you've posted/asked so far
