Hello JON,
Are you using FortiOS 5.4 and above? If you are, you can overwrite the blocking by adding the following custom signature and setting it to Monitor:
F-SBID( --name "Libproxy.Nie.SSL_Custom"; --protocol tcp; --service SSL; --pattern "libproxy.nie.edu"; --context host; --no_case; --app_cat 6; --weight 40; )
