Err_ssl_protocol_error

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: https://pedidosydevoluciones.assaabloymexico.com:93/

I ran this command: Open the browser (URL)

It produced this output: ERR_SSL_PROTOCOL_ERROR

My web server is (include version): IIS

The operating system my web server runs on is (include version): Windows Server

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don't know): power shell?

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):

I create a certificate using "Certify The Web", all was ok (I think), I can see the certificate and bind it to sites on IIS, but when I try to open the URL on the browser I'm getting the error: SSL_ERROR_RX_RECORD_TOO_LONG...

Another thing, when I was binding the port and certificate in IIS, I see 2 Certs almost equals, just the expiration month is not...

I run this command on powershell:

openssl s_client -connect pedidosydevoluciones.assaabloymexico.com:93 -msg
CONNECTED(00000194)

Your webserver is speaking plain http, not https: http://pedidosydevoluciones.assaabloymexico.com:93/

Hi @MaxS

checking your domain via https://check-your-website.server-daten.de/?q=pedidosydevoluciones.assaabloymexico.com#ct-logs

You have created two certificates:

Issuer not before not after Domain names LE-Duplicate next LE
Let's Encrypt Authority X3 2020-03-11 2020-06-09 pedidosydevoluciones.assaabloymexico.com - 1 entries duplicate nr. 2
Let's Encrypt Authority X3 2020-03-11 2020-06-09 pedidosydevoluciones.assaabloymexico.com - 1 entries duplicate nr. 1

So that part works.

Port 93 is a http port. So share a screenshot of your binding. Change that to https and select the certificate.

Thank you…

I verified the binding and it’s what we have:

The binding is on port 93, https y selected the cert…

Looks like that binding isn’t used.

Add your domain name pedidosydevoluciones.assaabloymexico.com in the “Host name” field, check “Require Server Name Indication”.

I changed but still the error…

Looks like you use the wrong machine.

Checking

http://pedidosydevoluciones.assaabloymexico.com:93/

there is a proxy error:

502 - Web server received an invalid response while acting as a gateway or proxy server.

There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server.

Looks like you have two machines.

http redirects to

http://pedidosydevoluciones.assaabloymexico.com/Identity/Account/Login?ReturnUrl=%2F

There are some sites on same address, each port used is a distinct site, but is the same server and same IIS… Right now, port 80 is not using https and it is what are you seeing without the port 93…

Is there the posibility that the port (93) is restricted to use only http traffic?

But why is there a proxy error? Proxy -> second machine.

Why is there a http status 502?
