The remote host has been compromised and is running a 'Backdoor' program
The remote SSL server is using a certificate which has been revoked. The particular SSL certificate has a serial number of '\x04\x7e\xcb\xe9\xfc\xa5\x5f\x7b\xd0\x9e\xae\x36\xe1\x0c\xae\x1e' and an Issuer of USERTRUST.
There is a high probability that your server has been compromised. You should manually inspect and fix this system.
