How to configure SSL Passthrough？

[xricky]

I have recently been using the nghttpx for grpcs. I can secure an Ingress by specifying a secret, but SSL Passthrough
Can't succeed。 What is the function of “ingress.zlab.co.jp/backend-config: '{"peer0-tdpowf36e1": {"7051": {"proto": "h2","tls": true，“sni”： “xxxx"}}}'”? Thanks

SSL Passthrough is not supported.
