External Captive Portal HTTPS problem with PepWave Max BR1 LTE ET


I’ve set up an External Captive Portal successfully last year, everything was working ok but recently I am experiencing problems, at step 5 of external captive portal, when user sends HTTPS request to captive-portal.peplink.com browser shows “NET::ERR_CERT_DATE_INVALID” and user HAVE TO manually accept that warni and continue to HTTPS://captive-portal.peplink.com.

How can I solve this certificate problem?

I have provided feedback here.
