Business Video Conference Site Blocked

gzartman
I've got SSL Filtering setup with transparent proxy and it is blocking a business video conference site and I can't seem to figure out why.  The site is called zoom.us.   I have talked with the support folks at zoom and they say go create exceptions for .zoom.us and *.zoomsvr.com.  So, I created the following:

^https?://[A-Za-z0-9.-]*\.zoom\.us/
^http?://[A-Za-z0-9.-]*\.zoom\.us/
^https?://[A-Za-z0-9.-]*\.zoomsvr\.com/
^http?://[A-Za-z0-9.-]*\.zoomsvr\.com/

Connection to the video conferencing is still being blocked (works fine with filtering shut off).  

I pulled up the live log for web filtering and I'm not seeing any blocked log entries.  The only entry that stands out are these 2 ssl error entries:

2014:04:22-23:09:13 gateway httpproxy[17663]: id="0003" severity="info" sys="SecureWeb" sub="http" request="0xd880ee0" function="ssl_log_errors" file="ssl.c" line="86" message="C 192.168.0.102: 4090403696:error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca:s3_pkt.c:1256:SSL alert number 48"

2014:04:22-23:09:13 gateway httpproxy[17663]: id="0003" severity="info" sys="SecureWeb" sub="http" request="0xd880ee0" function="ssl_log_errors" file="ssl.c" line="86" message="C 192.168.0.102: 4090403696:error:140940E5:SSL routines:SSL3_READ_BYTES:ssl handshake failure:s3_pkt.c:989:"


I'm not sure if this is associated with the video conferencing or not. 

Any suggestions on how to track this down?

Thanks

Greg

    A quick follow-up:

    I setup my client machine to connect directly to the proxy server so that I wasn't using transparent proxy and the video conference connection works fine.  Seems this is just an issue with transparent proxy.

    Is their a way to fix this?

    Thanks,

    Greg
