Sorry, i was using de incorrect file, the file import_users.py that i was using is at the location /home/user/iRedAdmin-Pro-SQL-4.6/tools/

now i see there is another file import_users.py in /opt/www/iredadmin/tools/, i already edited with all info, now i get Login failed, im using postmaster wich is the master admin, now what im doing wrong?

no error, only get: Login failed
That's all.

I was using an ip in System Settings, i remove the ips in the "RESTful API is accessible only from specified IP addresses or networks"

now, i get this error:

<<< ERROR >>> line has invalid user email address:
b'test@domain.com, PassWord,2048, Test,'
