Login to ESET ERA web console failed

Login to ESET virtual appliance failed with message Connection failed with state "Not Connected"
This happens after ERA updates and restarts.
Solution is to edit MySQL configuration file located at /etc/opt/eset/RemoteAdministrator/Server/StartupConfiguration.ini
with right connection string. Issue command as root or sudo:

sed -i 's/MySQL ODBC 5.3/MySQL ODBC 8.0/g' /etc/opt/eset/RemoteAdministrator/Server/StartupConfiguration.ini
this command just replaces MySQL ODBC 5.3 to MySQL ODBC 8.0 in connection string.
After that restart MySQL:

service mysqld restart

and restart era service

service eraserver restart
