Troubleshooting Tips
- If you are using a 3M self-check machine, the checkin option must be set to Yes, due to a 3M requirement for enabling initial communication. If you do not want the check-in action to be allowed, ensure that you block it when configuring your 3M self-check machine. If you do not define the checkin option, you will not be able to activate the integration.
- Due dates are not displayed – if this used to work, it might be related to daylight saving times change. The date format in the machine’s software should be updated to match the Alma date format. It is also possible to define Alma to return the due date field (AH) without time zone (use_time_format_with_time_zone_in_self_check customer parameter),
- “Connection timed out” messages in the stunnel log – add the following line to stunnel.conf:
TIMEOUTidle = 86400
