Lync 2013 reverse proxy unstable

I just configured my first iApp with LTM (v.11.2.1). It worked well to start but then after a few hours all the web services stopped working. For example, https://meet.domain.com would give a "could not establish a secure connection" error in any browser. When testing directly against the internal Lync Front End, it works. Also, mobile device would not log.

 

After a few more hours, everything would start work again.

 

I can add that everything works well from inside... meaning when we remove LTM from the Lync services equation.

 

I am using our internet PKI using a SHA1 SAN certificate. I'm not sure if I need to specify our Chain, Trusted CA in either client or server certificate.

 

Any hints on how to fix this or how to configure my certificates in my different profiles?

 

Thanks

    And by the way, when the VS is not working, if I go into its properties and just click the Update button, even without changing anything, it starts to work again right away. For a while... then it breaks again.

    OK, so could you provide some data around your setup etc.

     

    -VE or physical?

     

    -Uptime?

     

    -Any useful log messages?

     

    -CPU & memory usage?

     

    -SSL Profile settings?

     

    -Anything else useful?

     

    -Have you tried doing a packet capture whilst the issue is occurring, client side in particular

     

    -Server metrics?

    Duplicate IP in our DMZ. An old server had multiple ip configured and one of them was the one I was using for my VS.
