This usually means that Firefox wasn't able to find a cipher suites to use
to connect to this server and reached the end of the list.
There can be two possibilities: one is that the server is outdated and
doesn't support modern cipher suites, another might be that the server
only supports a few cipher suites and Firefox doesn't support any of these.
You can check your browser and possibly compare this with the
server setup.

BitDefender and ESET that intercept secure
connection certificates and send their own.
