Whiteboard & Powerpoint share failing !!

Question

Hello All,
I am having issues with sharing the Whiteboard and Powerpoint with external users. The error which I am getting is "Some sharing features are unavailable due to server connectivity issues" which seems to be a generic error. I cant say if the desktop sharing
is working 100% fine as it works 7/10 times.
I found that the certificate which is assigned to my reverse proxy server is a wild card certificate and does not have Meet, or dial in url as Subject alternative name as suggested in
http://technet.microsoft.com/en-us/library/gg429704.aspx.
Now, my question is :
Is my problem because of the certificate which I have? (I dont believe so, cos if that is the case the Meet url itself should fail which is not hapening in my case.)
Or the cause could be something else?
Regards
NS

Hello All,
A very very happy new yr to all...!!
Well, my issue is still not resolved. I feel my proxy server perfectly fine as my issue of Whiteboard, Powerpoint and Polling sharing is only while using the Lync attendee.. Which means its a Web conferencing edge problem. I looked into my edge server and
I noticed an event id which gives me hint that the edge conferencing is not able to reach the front end conferencing..!! Here is the event id :-
Log Name:      Lync Server
Source:        LS Web Conferencing Edge Server
Event ID:      41987
Task Category: (1023)
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      LyncEdge.xxxx.COM
Description:
Server connection failed to establish.
Over the past 121 minutes Lync Server has experienced TLS outgoing connection failures 1 time(s). The error code of the last failure is 0x80090308 (The token supplied to the function is invalid
) while trying to connect to the host "".
Cause: This can occur if the destination is not configured or unreachable from this host.
Resolution:
Check your topology configuration to ensure the destination host can be reached and is a valid Web Conferencing Server configured to accept connections.
I tried restarting the Front End conferencing service as well, still no help...
