Registering CentOS 7 client - Question and salt state error

Good Morning, Can you please assist me with two questions whilst I am trying to get familiar with the salt minions/registration? (Background: AlmaLinux 8 Uyuni Server 2021.12 / CentOS7 client) 1. Bootstrapping the CentOS7 client manually does work. It took me a long time to accept the key on the master (multitasking/dinner). The minion tried to contact the server a few times but then not anymore (it seems). I had to manually restart "venv-salt-minion.service" on the client. Is this the expected behavior? 2. Failed to apply state(s): highstate I have quite some errors when applying the initial state to the minion. Are these error messages from the server or from the client?
