Hello!

Just to be sure, I’m starting a separate thread so it doesn’t get overlooked Wink

I’d like to report an issue with the HTTPS example from the reference:
1. First issue – the attached certificates have been invalid for some time now.

2. Even after connecting new valid certificates (self-signed), when I enter https://localhost:4000 into the browser, an error message appears in the browser window:

The localhost server is using an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH

And in the application logs:

Connection accepted
SSL handshake failed: socket(568) / SSL handshake: Unknown error code.
===================================================== Waiting...

Hi przem_kaz:

Maybe the server.crt expiry date expired.

You need to create a new server.crt and server.key file according to the following method.

//1. Gen CA file. myca.key, myca.cert
openssl genrsa -aes256 -out myca.key 2048
openssl rsa -in myca.key -out myca.key
openssl req -new -x509 -days 3650 -key myca.key -out myca.crt -subj "/C=CN/ST=SD/L=YT/O=xx/OU=CA/CN=MYCA/emailAddress=youremail@xxx.com"

//2. gen server.key and server.crt
openssl genrsa -aes256 -out server.key 2048
openssl rsa in server.key -out server.key

openssl req -new -key server.key -out server.csr -subj
"/C=CN/ST=SD/L=YT/O=xxx/OU=RD/CN=xxx/emailAddress=youremail@xxx.com"

openssl x509 -req -days 3650 -in server.csr -CA myca.crt -CAkey myca.key -CAcreateserial -out server.crt

Hi zouql
Thank you for your suggestions.

I tried using the new certificate, as I mentioned in my first message
But just to be sure, I tried your suggestion using OpenSSL (on my first attempt, I used the XCA tool to create a new certificate)
I’m getting the same results – it doesn’t work.

Could you please try compiling the HTTPS reference code and let me know if it works for you?

Hi przem_kaz:

These are the server.crt and server.key files I generated. Replace the two files in the code directory, compile and run. This is the result in the browser.

If you encounter a warning page, click "advanced", and then Continue to...，You will see the result page.

Hi Zouql,
I just realized today that I hadn't replied to your post.

I can confirm that the HTTPS reference app works fine with your certificate—I messed something up when I tried to create a new certificate using the XCA app.

Thanks for your help.
