Secure Connection Failed

Alberto Aresi

I have one site and only one, that is giving me headache.

https://ec.synnex.com/ecx/

It's a national IT distributor and when I try to connect I receive the error (Firefox browser, slightly different messages with other browsers but same result)

Secure Connection Failed

An error occurred during a connection to ec.synnex.com. SSL received a malformed Handshake record.

Error code: SSL_ERROR_RX_MALFORMED_HANDSHAKE

    The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
    Please contact the website owners to inform them of this problem.

I tried to go to Protect - Web - Exception

Added these lines, one by one, but after every try, I always get the same error message

    Hi Alberto Aresi,

    I tried to replicate your issue in my LAB with Default Workplace web filtering policy with HTTPS Decrypt and Scan and I am able to access the website without any issues. I did have to add any exceptions for the website. 

    However, the exception you created should bypass any traffic to that specific website. 

    Do you see any request to the website being blocked on the firewall? Please check Log viewer logs and filter all the logs with your workstations IP address. 

    You can change the log view to detailed view to see logs for all the modules. 

    For testing, could you please create new firewall rule with only one workstation IP address in source network and do not apply any advanced filters? Let us know if that works. 

    Thanks,

    Hi Patel

    this is what I find in the log

    and for what concerns LAN to WAN traffic rules I don't have any filter active

    I also just upgraded firmware to XG106 (SFOS 18.0.0 GA-Build339) but the result remains the same.

    Thanks

    We are also experiencing the same exact issue with the same exact site.  We are on SFOS 18.0.0 GA-Build354.  When I contacted support they told me to follow https://community.sophos.com/kb/en-us/123048.  I had installed the certs but still have the same end result.  We also have tried turning off QUIC and Https scanning on our LAN to WAN rule.  

    Is there any possible new information on this?

    Hi Jeffery Fisch,

    What is the uptime on the firewall? 

    If you have followed the instructions provided by the support team, I would advise you to reboot the firewall that will restart the firewall and let us know how it turns or for you. 

    Could you also PM me the support case number? 

    Thanks,
