PVE 的管理页面是自签证书 https 的，如何借助 frp 外网访问？

家里一台机器安装了 pve(proxmox virtual environment)。在内网通过 https://10.10.10.3:8006 访问

点击 Proceed 即可正常访问（忽略这个警告即可）

VPS 上 frps 已部署好，内网 frpc 也已经配置好（内网配置如下）

[pve-dashboard]
type = http
custom_domains = pve.example.com
local_ip = 10.10.10.3
local_port = 8006
remote_port = 81
use_compression = true
use_encryption = true

frpc 这边日志显示 proxy 建立成功

[control.go:181] [0e57994403b3976e] [admin.pve-dashboard] start proxy success

但是访问 https://pve.example.com 是 frp 的默认 404 页面（如下图）。

我在 frp http 传输外层包了一层 nginx ，最外层套了 SSL 实现的 https 访问

有人知道这种情况下应该怎么做吗？

内网中，curl -v http://10.10.10.3:8006 结果如下，

* Empty reply from server
* Connection #0 to host 10.10.10.3 left intact

scheme 必须指定是 https 才行，curl -v https://10.10.10.3:8006

*   Trying 10.10.10.3:8006...
* Connected to 10.10.10.3 (10.10.10.3) port 8006 (#0)

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and

这种自签证书的 web 服务可以通过 frp 暴露在公网吗，还请指教。
