Before the grade changes which took place in January, SSL Labs reported that my webserver supports SCSV. Now it doesn't. My webserver uses the latest mbed TLS library, which has SCSV support. I've also tried the sslscan tool and that one says my webserver has SCSV support. Could this be a bug in SSL Labs?
If you want to test for yourself, my webserver / website is https://www.hiawatha-webserver.org/.
