Whenever I visit my [[website|https://alotofyoumaybeaskingwhyareyouavirginisaytothemiampoggersgfisnot.international/]] I get an error saying Cannot communicate securely with peer: no common encryption algorithm(s). And the error code is SSL_ERROR_NO_CYPHER_OVERLAP. I am running Firefox 90.0.2 on Windows 10. The website is hosted on a nginx vps and I am using Cloudflare for SSL. On cloudflare I am using a single A record to the IP of my VPS and I have enabled proxy. SSL/TLS encryption mode is Flexible.

One tool to extract a list of the encryption cipher supported on the server is to test the site on this service:

https://www.ssllabs.com/ssltest/

They also report which browsers in their testbed are able to connect so you can see whether this is a more general issue or just you.

Microsoft Edge gives a similar error. So no.

Hi

I have run a WHOIS trace and am not seeing anything that looks odd. I recommend that you contact the support team of the site provider for help with this issue.

Does your hosting provider have any guides on how to configure SSL on their servers? Sometimes they have forums.
