Something went wrong after logging into OWA

Randomly when users login to OWA they are getting the something went wrong error pictured below with event ID 1003 . This started after updating to exchange CU 14. I've tried uninstalling/reinstalling DUO and installing a newer version of DUO but this is still randomly happening for users no matter which server they connect to.

[Owa] An internal server error occurred. The unhandled exception was: DuoUniversal.DuoException: Invalid state parameter. Authorization could not be completed.
at Duo.DuoWebHttpMod.DuoAuthenticateRequest(HttpContext context, String username, LogBuilder log)

I found the DUO IIS Integration event log and it says 

No Duo cookie found
Caught exception while processing request: DuoUniversal.DuoException: Invalid state parameter. Authorization could not be completed.

Hello,

we have the same problem. The load balancer settings are all configured according to the instructions. Is there already a helpful solution for this?
