Alternatively / if above fails to succeed, you can scan your (current) supported list of algorithm with different tools / links: For browser side you might connect to e.g. either https://browserleaks.com/ssl or https://clienttest.ssllabs.com:8443/ssltest/viewMyClient.html in order to see the list of supported algorithms. Do that with both your Windows as well with the browsers on Ubuntu. For server side you need to scan your server. If if is available from internet you might use https://www.ssllabs.com/ssltest/ But there are also different tools to scan internal servers, e.g. https://github.com/iSECPartners/sslyze On https://github.com/edelahozuah/awesome-tls-security you'll find an even more complete list of tools.

Easiest and most recommended: Use the Mozilla SSL Configuration Generator to configure a recommended configuration. Start with the "Intermediate" option, but when successful you might later also test the "modern" option. Don't use option you fully understand. As you have connectivity issue first start with an a bit less secure set of options in order to first ensure, you can have a successful connection. Depending on your nginx / openssl version, a good starting set might be this link: https://ssl-config.mozilla.org/#server=nginx&version=1.22.1&config=intermediate&openssl=1.1.1s&hsts=false&ocsp=false&guideline=5.6
