What are the current cipher suites supported by Azure Front Door? Can somebody suggest what could be the possible reason for such behaviour. In the past, Firefox has struggled with this considerably to the point where 7-8 certificate re-issues will cause significant latency, and 10 or more can cause the handshake to take upwards of 30 seconds. While 256-bit encryption is still sufficiently robust, the real security is at the gate where a much larger, much stronger private key (generally a 2048-bit RSA key) helps handle the authentication portion of the connection. To remedy this, youre going to need to find and install the missing intermediate certificate. Edit the order of the cipher suites to ensure that these four suites are at the top of the list (the highest priority). At the beginning of every HTTPS connection, the client (the internet users web browser) and the server (hosting the website) must go through a series of checks for lack of a better term to authenticate one another and determine the parameters of the encrypted connection.
