Why does one website get blocked but a similar one does not?

SteveGross

I am trying to block a couple of bad websites.  I went into base policy and created a list of sites, including "*.badsite1.com" and "*.badsite2.com".  The first site is blocked with a message of "an error occurred while handling your request" and "connection refused".  The second site gets the message of "Content blocked" with a button that allows for unblocking.  Why the difference?

Here's the log entries for each site:

2018:04:18-16:43:28 tsefw-1 httpproxy[5784]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="GET" srcip="172.24.32.252" dstip="209.239.175.95" user="" group="" ad_domain="" statuscode="502" cached="0" profile="REF_DefaultHTTPProfile (Default Web Filter Profile)" filteraction="REF_DefaultHTTPCFFBlockAction (Default content filter block action)" size="2543" request="0x1db71000" url="http://www.badsite1.com/" referer="" error="Connection refused" authtime="0" dnstime="88" cattime="110" avscantime="0" fullreqtime="57988" device="0" auth="0" ua="Mozilla/5.0 (Windows NT 5.2; rv:47.0) Gecko/20100101 Firefox/47.0" exceptions="" category="130" reputation="malicious" categoryname="Malicious Sites"

    Hello SteveGross,

    I'm not familiar with the UTM but ...
    a similar one
    on a higher level perhaps though badsite1 has reputation="malicious" categoryname="Malicious Sites" whereas badsite2 reputation="neutral" categoryname="Pornography", note also that for the former no reason tag is logged, for the latter it's reason="category". This might explain the different behaviour.

    Thanks Christian.  I think this would mean that the emails get processed first by something other than the Default Block Policy.  Would anyone know what that is?

    Hello SteveGross,

    emails
    emails? Isn't this about web and HTTP?
    I hoped that some UTM expert (like Bob - ) would give a more helpful answer - just threw in my two cents when I saw that you query was unanswered for "many hours" [:)].

    First of all, I noticed statuscode="502" together with error="Connection refused" in the first entry so maybe the destination did actually refuse the connection.
    But anyway, I'd have thought that a blacklist/whitelist would have precedence - how did you add it to your policy?
