Resolving autohopper and other issues

Project Title: VICIdial Campaign Hopper Issue Troubleshooting

Project Overview
I have a working call center environment where VICIdial is integrated with 3CX. The system was previously functioning correctly — when leads were uploaded into VICIdial, they automatically entered the hopper and outbound calls started normally.

Current System Setup
- VICIdial installed and operational
- Connected to 3CX PBX
- Campaign created and active
- Lead lists uploaded successfully
- Lists assigned to campaign
- Calling previously worked without issues

Problem Description
After uploading new leads, they no longer move into the hopper. As a result, outbound dialing does not start. The leads remain in the list database but are not processed for dialing.

Troubleshooting Performed
- Verified campaign status is ACTIVE
- Confirmed list is ACTIVE and assigned to campaign
- Checked dialing method and campaign settings
- Restarted services and attempted manual fixes
- Made configuration adjustments, but issue persists

Expected Result
Uploaded leads should populate the VICIdial hopper automatically and begin dialing through 3CX.

Requested Assistance
Need diagnosis and resolution of why leads are not entering the hopper and restoration of normal outbound dialing functionality.
