I haven't been able to access the https://opendatakit.org website since yesterday. Both Google Chrome and Kaspersky won't let me do so because "The certificates of the website are not valid". According to "SSL Checker", the certificate expired 2 days ago.
This is the error I get from different devices (tried with two computers and mobile phone) and different internet connections (Wifi and Mobile Data):
Am I the only one unable to access? The reason why I have been trying to access is to download the latest apk of ODK Collect. Any help with this is appreciated.
Thanks in advance.
