Every certain amount of seconds, I see this in logs:
It is something wrong with the installation?Jul 21 23:52:25 server postfix/submission/smtpd[75940]: connect from localhost[127.0.0.1]
Jul 21 23:52:25 server mariadbd[1093]: 2021-07-21 23:52:25 3128 [Warning] Aborted connection 3128 to db: 'unconnected' user: 'unauthenticated' host: 'localhost' (This connection closed normally without authentication)

Still the server is not in production, I am migrating all from i-MSCP, but I want to make sure that this will not cause any problems later.
Thanks in advance.
EDIT 1: Also, just in case if is related, the only warning I had during installation was:
EDIT 2: also, I found this:db | UPDATE `mysql`.`user` SET `Password` = PASSWORD('***DB_ROOT_PASS***') WHERE `User` = 'root'
Database error: SQLSTATE[HY000]: General error: 1356 View 'mysql.user' references invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them
