Keep getting errors when using https

My question:
I’m trying to send a request using my API and postman keeps showing below error.

Error: write EPROTO 140634396975224:error:100000f7:SSL routines:OPENSSL_internal:WRONG_VERSION_NUMBER:…/…/third_party/boringssl/src/ssl/tls_record.cc:242:

Details (like screenshots):

I’ve already tried:
Replacing https with http isn’t working either as my internet service blocks it for security reason.
I turned off SSL verification on setting and tried disabled all combinations of tsl version but none of them have worked. Localhost with http is working well with my APIs, so my endpoints are working fine. I would appreciate it if anyone can give insight to resolve this issue. Thanks!
