@sourcaffeine You’re not at all having the same issue.
The old client isn’t really supported any more. Please understand that the messages you’re seeing in the fog.log file are totally different and give an overall picture.
Basically, the messages are saying the CA you’re using are not the CA that was generated for the FOG Server.
You can retry this with:
./installfog.sh --recreateCA -y
I can’t be sure what spawned the issue to begin with though. It also means after you recreate the CA certificates, you will need to reinstall the client to get the client to repin the updated CA chain information.
