Here are my error.log -

2021/09/17 11:23:09 [error] 9429#9429: *1814357 peer closed connection in SSL handshake (104: Connection reset by peer) while SSL handshaking to upstream, client: 10.0.22.99, server: xxx.xxxx.xxx.xxx, request: "GET /TestPage/ HTTP/1.1", upstream: "https://10.0.20.77:443/TestPage/", host: "xx.xxx.xxx.xx"

Wondering why this is making connection to host when my proxy_pass says https://<Host_name>
