SSL problem

3 years ago in bOS Server • updated by 1 month ago • 5

Hi All. Just started today to get the error ERR_SSL_VERSION_OR_CIPHER_MISMATCH when I access through https.

This also makes Alexa not to work.

How can I solve this? I'm using windows 7 as a server.

Thanks

Best regards

Hello Francisco,

this could be an issue with the windows version (windows 7), if possible, we'd suggest updating to windows 10.

Best regards.

The error ERR_SSL_VERSION_OR_CIPHER_MISMATCH usually means your server is using outdated SSL/TLS protocols or ciphers. Since you're on Windows 7, enable TLS 1.2 (1.0 and 1.1 are deprecated). You can do this via Internet Options → Advanced tab → check "Use TLS 1.2". Also, update your server's SSL Certificate and ensure it's not using weak ciphers. Consider updating Windows 7 with all the latest security updates or using the IIS Crypto tool to easily fix cipher issues. Hope it helps!

I am recently having the same issues... I have checked my windows 11 Internet Options and "Use TLS 1.2" was already checked. How do I update my server SSL certificate?

Just for your info, I can connect via BOS config but I cant neither via App nor via BOS client.

Thank you
