Been trying to upgrade our netbox server from v3.1.11 to the latest version. I've tried updating to different earlier versions but keep getting the same error. I've searched for an answer to no avail.

Python version
3.8.10

PostgreSQL version
12.12

Steps to Reproduce
Performed the migration following https://docs.netbox.dev/en/stable/installation/upgrading.
3.1.11 to any version

ran ./upgrade.sh

Expected Behavior
upgrade.sh returning no errors.

Observed Behavior
Successfully installed django-auth-ldap-4.1.0 pyasn1-modules-0.2.8 python-ldap-3.4.3

The update ends here and the netbox services will not start. I've checked the ALLOWED_HOSTS entry in the configuration.py file and it seems to be correctly configured according to the Netbox docs. Any help would be appreciated.

django.core.exceptions.ImproperlyConfigured: The ALLOWED_HOSTS setting must be a list or a tuple.

Please show your ALLOWED_HOSTS configuration and we will point out what's the problem.

Thank you for getting back to me. After taking the weekend off I figured out what the issue was with the ALLOWED_HOSTS config. Fixed it this morning and was able to perform the update to 3.4.2. Thanks again for your response.
