We have several sites set up on our ISA server, including reverse proxy for an older MOC 2007 R2 install (upgrading to Lync pending) however several of the sites that use a wildcard SSL cert are no longer functioning.
Chrome throws this error:
Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error.
Firefox throws this one:
SSL received a record that exceeded the maximum permissible length. (Error code: ssl_error_rx_record_too_long)
Another site that is run through the ISA server that doesn't use the wildcard cert but uses a premium EV SSL is working just fine.
I've tried reinstalling the same cert as well as running a restore operation from our backups, the restored server (from Wednesday of last week) exhibits the same problems.
I've also deleted the rule and re-created it, and it's the same problem.
I'm at a loss.
