Please try this:

Go the PC that keeps getting these messages in its logs.  Run:

$ chrony

chronyc> password
password: <manually_enter_your_chrony_Passwd>

If the passwd is wrong, or some characters are incompatible with the terminal, 
then you will get:

"Password: 501 Not authorised --- Reply not authenticated"


You can test this by entering the wrong passwd initially.  Unfortunately, I no 
longer have the PC running chrony to test it here.
