我在我的 VPS 上安装了 Ubuntu 20。这就是我尝试这样做的原因：
curl -v https://imenik.tportal.hr/show?action=pretraga&type=bijeleStranice
[1] 438975
root@vps:/var/www/html/tportal# * Trying 195.29.166.100:443...
* TCP_NODELAY set

* Closing connection 0
curl: (35) error:1425F102:SSL routines:ssl_choose_client_version:unsupported protocol
但是当我这样尝试时，它有点工作
