  • @Tom-Elliott Working again as of rc 31. Thank you!!!


  • Senior Developer

    RC 31 released, along with v0.11.7 of the client. Please update and let us know if things are working properly.

    Thank you,



  • @Joe-Schmitt OK! Thank You!!!


  • Senior Developer

    @dureal99d until 0.11.7 is released (which should be within a day), you can simply delete the Mono.Security.dll file present in the fog-service directory. Then restart the service.



  • @dureal99d Don’t worry about what I said, Joe just (re)confirmed it is a bug.

    @Joe-Schmitt what version of Mono could they install in the mean time to work around the issue?



  • The fog server doe not give me an option in the gui to reset encryption any linux based host only windows based.


  • Senior Developer

    I’ve verified that the issue started with 0.11.5 on mono systems. It’s an issue with a library that I use requesting a specific version of mono to be present. I’ll start working on a patch.



  • Go to that host in host management and click “Reset Encryption”. You can also do this for groups.
