Getting error "JAR resources in JNLP file are not signed by the same certificate" after iDRAC update

I updated my M610 iDRACs from 3.75 to 3.80 and now I'm getting an error when trying to run the virtual console: "JAR resources in JNLP file are not signed by the same certificate".

Anyone seen this and know the solution? I've tried clearing my Java cache and my browser cache but that doesn't help. If I run the virtual console from another desktop machine it works fine.

Thanks.
