I have Ubuntu Server 20.04 Yesterday I'd spent some time trying to open port to my application from outside web. So I was googling how to accomplish that task and made a lot manipulations with iptables (even not fully understanding what I am doing). Now It's ok, and I can access it from outside, but I can't access any resources by https.

curl https://mail.ru
curl: (35) error:1408F10B:SSL routines:ssl3_get_record:wrong version number

What does it means and how can I fix it? Thanks

Additional info:

sudo ufw status
Status: inactive

This can be one of possibilities :

  • You have IP entry for that domain in your hosts file, but your DNS also resolve that domain in another IP
  • One of ? possibilities - did you mean to add another option? – Artur Meinild Feb 22 at 9:01
