Used/Expired voucher can still be used to authenticate
Hi!
I need your help. I am using hotspot authentication on my wifi. I generated voucher codes for 1Gb for 1 day, 7Gb for 7 days and 30Gb for 30 days. Just recently, I noticed that one of my users used the expired code and was successfully accepted by the system. The code that my user has purchased is 7Gb for 7 days and can be used by 2 users simultaneously. The user consumed 7Gb only in 3 days and tried the same code again and it worked. I unathenticated the user and tried the code myself and it successfully connected to the net. This does not happen to 1Gb codes and only noticed this on 7Gb codes so far.
I have attached screenshots for your reference.
I have omada V4.15 firmare: 1.7.0 Build 20200703 Rel.59609
Is there anything I might have done wrong? Your inputs are highly appreciated. Thank you in advance.
This is an old voucher code I tried in my device. It was first used on 25 July and expired after 7 days. I tried the expired code today and suprisingly, it worked. The user only consumed 700mb. But still, it should only be valid for 7 days which already expired on 1 Aug. After I tried the code, I checked it in voucher manager as seen below.
Here is the voucher details:
In the previous omada controller software, as soon as the user enters the code it automatically shows "expired" when you check in the voucher manager. In the new version, it only shows all the voucher but not does not tag it whether it's been used or not.
