I am not able to access my server through domain name. Its showing 502 Bad Gateway.
Error log showing SSL_do_handshake() failed.
But its running successfully when i access through ip address.
/etc/nginx/sites-available/default file
/var/log/nginx/error.log showing this error -
[error] 13728#13728: *1 SSL_do_handshake() failed (SSL: error:1408F10B:SSL routines:ssl3_get_record:wrong version number) while SSL handshaking to upstream, client: 179.43.169.181, server: www.myvaccinenotifier.me, request: "GET / HTTP/1.1", upstream: "https://128.199.21.142:3000/", host: "myvaccinenotifier.me"
Probably its due to some mistage in nginx configuration... Help me correct it.
PS: I'm new to this.
Not much is known about your setup, but one can make the following observations:
proxy_pass http://127.0.0.1:3000, which suggests that there is some internal server on port 3000 and that nginx should work as reverse proxyproxy_pass https://128.199.21.142:3000/, i.e. same port as with HTTP but different IP address and especially also a different protocol to access the upstream, i.e. https:// instead of http://.https:// and not http://. It is very unlikely that the app supports both HTTP and HTTPS on the same port, so it is likely that it should have been http:// and not https:// to access the internal application. This is actually a common problem and the "wrong version number" is a common error message seen with such a broken setup.Recommendations:
proxy_pass https://128.199.21.142:3000/ to proxy_pass http://127.0.0.1:3000, i.e. exactly the same upstream for port 80 http and port 443 https.
