Requests through proxy

Greetings!
I have a problem running axios with configured proxy.
I'm creating a tool to validate proxy lists.
To check if proxy is active I use its credentials as

axios.get(SOME_URL, {
  proxy: {
    host: proxy.host, // 81.162.195.121
    post: proxy.port // 3128
  }
})

And i receive either timeout error (thats OK) or write EPROTO 14216:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:openssl\ssl\record\ssl3_record.c:252:

I assume that this proxy is alive but something goes wrong.
Would be thankful for any hints!

Thank you in advance!

PS: Proxies are actually alive. Checked with request lib.

Context
