Plugins » Salt

I have a running Foreman <-> Salt Setup with smart Proxy configured.
I am able to:
- Import salt Environment
- Import salt states
- edit autosign.conf
- view salt keys

If I want to edit salt States, I get an Error Page "We're sorry, but something went wrong. If you are the application owner check the logs for more Information"

logfile is attached.

Foreman was installed via installer, smartproxy to salt and salt-api are configured manually.
Running config:
Foreman 1.18.1
salt: salt-master 2017.7.7 (Nitrogen)

Thank you
Matthias
