OpenSSL can't connect some servers

Posted on June 27, 2022

Hello,

I got timeout error while connecting servers with openssl. I had openssl 1.1.1g version on my droplet. When I try on Amazon EC2 I can connect to server and getting information about SSL Cert. But on the DO I couldn’t.

I upgraded openssl but I took same output. Therefore I couldn’t run my python script and couldn’t processing outputs.

Linux kali 5.8.0-kali2-amd64 #1 SMP Debian 5.8.10-1kali1 (2020-09-22) x86_64 GNU/Linux

Hi there,

Is it possible that the server that you are trying to connect to has its 443 port closed for the world and is only accessible via your AWS VPC?

If you try to run a telnet server_name 443 does this work?

If the telnet command also fails, then it would indicate that it is a network issue rather than an OpenSSL issue. It is possible that the firewall on the server that you are trying to connect to is blocking your server IP.

Best,

Bobby
