【问题描述】：
所有，
我有一个网站，可以通过端口 86 很好地通过 HTTP 访问。现在需要添加 SSL 来保护连接。该网站由 thttpd 网络服务器提供服务，是的，它不支持 SSL。我当时通过谷歌搜索了很多。建议通过 Stunnel 将 SSL 添加到 thttpd。
更新：
这是我的 stunnel.conf：
; Sample stunnel configuration file for Unix by Michal Trojnara 2002-2013
; Some options used here may be inadequate for your particular configuration
; This sample file does *not* represent stunnel.conf defaults
; Please consult the manual for detailed description of available options

; A copy of some devices and system files is needed within the chroot jail
; Chroot conflicts with configuration file reload and many other features
chroot = /usr/local/var/lib/stunnel/
; Chroot jail can be escaped if setuid option is not used
setuid = nobody
setgid = nogroup
fips = no
; PID is created inside the chroot jail
pid = /stunnel.pid
; Debugging stuff (may useful for troubleshooting)
;debug = 7
;output = stunnel.log

; Certificate/key is needed in server mode and optional in client mode
cert = /usr/local/etc/stunnel/stunnel.pem
;key = /usr/local/etc/stunnel/mail.pem
; Authentication stuff needs to be configured to prevent MITM attacks
; It is not enabled by default!
;verify = 2
; Don't forget to c_rehash CApath
; CApath is located inside chroot jail
;CApath = /certs

; Don't forget to c_rehash CRLpath
; CRLpath is located inside chroot jail
;CRLpath = /crls
; Alternatively CRLfile can be used

[https]
accept = 443
connect = 86
; "TIMEOUTclose = 0" is a workaround for a design flaw in Microsoft SSL
; Microsoft implementations do not use SSL close-notify alert and thus
; they are vulnerable to truncation attacks
;TIMEOUTclose = 0
; vim:ft=dosini
这是我得到的结果：

这里是运行/usr/local/bin/stunnel之前的端口监听信息：

这里是运行后的端口监听信息：

我现在不知道出了什么问题。任何建议将不胜感激。
添加：
如果我关闭防火墙，我可以通过https://<my-ip-address>成功访问。但是，我仍然收到此错误消息：
Error binding service [https] to 0.0.0.0:443
bind: Address already in use (98)
想知道为什么...
