Connection to Dropbox



  • Running 2.0.3-RELEASE (i386)

    Client PC's with the Dropbox client installed continually receive "Can't establish secure connection".

    Dropbox uses standard internet ports (80 and 443) to transfer data.

    I recently switched a client from the LAN connection to a guest WIFI connection on a seperate IP without a pfSense box on it and it connects to Dropbox just fine.

    I thought the default LAN firewall rules allowed 80 and 443 through by default.

    What am I missing experts?  Thanks for the help in advance.

    "What am I missing experts?"

    Umm hmm lets see - information that would help us help you for starters ;)

    If pfsense was blocking 443, then you would not be able to access ANY https site.

    What are you using for dns?  Opendns, GoogleDns, your ISP? Are you using a proxy?  A simple google for that error points to a opendns problem a while ago that caused that error.

    I would do a sniff of the traffic, verify your solving where your trying to go correctly, etc.

    the default rules would allow anything from lan net to ANY – have you altered these rules using pfblocker or any other sort of addon? etc.. etc..



  • I apologize wasting everyone's time with this thread.

    It was OpenDNS.  Something I should have checked immediately.  Crazy week.

    Have a good one.

    We all sometimes overlook the stupid stuff, not a big deal - and you didn't waste anyone's time.  People are here to help, or be helped, etc.

    Glad you got it sorted!



  • I assume it was a cert error with OpenDNS.  Although they say that's how it should work, I've had to drop their service for anything vert-related because it just doesn't work.
