1. Update the /etc/hosts file with the correct hostname that you want to be

2. Then on salt-minion stop salt-minion service

# systemctl stop salt-minion

OR

# service salt-minion stop

3. Delete the salt-minion keys. you need to find the salt-minion key location and then remote minion.pem and minion.pub keys.

# rm -rf /opt/salt/etc/pki/minion/minion.p*

/opt/salt/etc/pki/minion
    - minion.pem
    - minion.pub

Perform the following steps on the salt-master side to fix the hostname issue

1. Delete the salt-key for the respective server

# salt-key -d acg-vm1.acg.com

2. After that restart the salt-minion service on the client side.

# systemctl restart salt-minion

# systemctl status salt-minion

# service salt-minion status
