I'm currently using a VPN Service and just today I have encountered an error when trying to access the Amazon website only with the VPN service turned on. When VPN is off, no issue. I have used this VPN with Firefox for more than a year with no issues. The error message is: Error code: SSL_ERROR_NO_CYPHER_OVERLAP Cannot communicate securely with peer: no common encryption algorithm(s).

System: Running Windows 10 (current) Firefox 94.0.1 Express VPN (current) Avast Software (current)

SSL_ERROR_NO_CYPHER_OVERLAP Your server apparently doesn't offer any cipher suites necessary to establish a secure https connection that are supported in Firefox. You can check what kind of cipher suites Firefox can make use of by visiting; https://www.ssllabs.com/ssltest/viewMyClient.html

Firefox will just show the SSL_ERROR_NO_CYPHER_OVERLAP error when encountered any site using the RC4 cipher.
