When i try to open a localhost site get error about ssl-checker

[Silvano14]

In this case ssl-checker throws an error (so you must catch the promise), instead in other cases it's enough read the object from resolved function.
I will be happy if in this case the library doesn't throw an errore message but resolve the promise and get the usual message about certificate

I suspect that the problem is the protocol used by library, it is possible change that?

Can you please try using https?

Postman by https:

Library:
Error: write EPROTO 8213996431112:error:100000f7:SSL routines:OPENSSL_internal:WRONG_VERSION_NUMBER:../../third_party/boringssl/src/ssl/tls_record.cc:242: [1] [1] at WriteWrap.onWriteComplete [as oncomplete] (internal/stream_base_commons.js:87:16) { [1] errno: 'EPROTO', [1] code: 'EPROTO', [1] syscall: 'write' [1] }

I should definitely handle this case 👍, But it seems that you don't have a certificate installed.
Also, what do you expect to happen?

Or, leave the choice of protocol to the programmer
