'Unable to enter enable mode!'

[jasfree]

I am running the script against an ASA, and keep getting 'Unable to enter enable mode!'

============================== Firewall Policy Report v0.1 ==============================
Checking the input file and options entered are valid...
Enter global fw password for user 'freeman':
Testing asa username/password and device connectivity ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 100% 0:00:00
⚠️ WARNING - 'Unable to enter enable mode!'

The script ist ran using the following parameters:

(acl_report) gns3@gns3lab:~/firewall_policy_report-main$ python3 main.py -u freeman -n ACLreport20230919 -l ~/firewall_policy_report-main/

I have tried using the glob_user/glob_pass and user/pword with the same result.

What am I doing wrong? Should the username and password be in double quotes?
