I get the following message in Chrome version 49 but not at same sites in Firefox I tried disabling some features but still will not work.
This site can’t provide a secure connection
explore10.com uses an unsupported protocol.
ERR_SSL_VERSION_OR_CIPHER_MISMATCH
Hide details
The client and server don't support a common SSL protocol version or cipher suite. This is likely to be caused when the server needs RC4, which is no longer considered secure.
