Question

I am trying to connect my remote nginx server which is configured to use ssl.

I fired a command

$curl  https://10.73.80.197:8080/ 

but after that i am getting error. Here is the whole log-

Answer 1

as explained in several other articles:

curl: (35) error:1408F10B:SSL routines:ssl3_get_record:wrong version number

Curl returns "Unknown protocol"

this kind of curl error is often the result of using a web proxy over https instead of http

you should check your https_proxy env variable

if you have something like

https://myproxy.example.com:8080/

then you should change and set the following

https_proxy=http://myproxy.example.com:8080/
