Voucher "expired" but still access

[pierreda]

Hello,

I have installed an OpnSense portal with vouchers.
I tried to login. No problem. Authentication OK

To see how it works, I marked the login/voucher as "expired" to disconnect the client.
And the client stay connected !
I tried to switch WifI off/on ... it connect again.
I "forget" the network, switch back, give a password ... and connected without portal template !!
I delete the entry ... no change

Finally, I change the Captive Portal template (other authentication) and ... YES ... I had to give credentials.

Strange isn't it?

Any explanation?

Thanks a lot

ps: sorry for my english ..
