Unable to connect to the moodle site on Moodle Apps

Dear Sir/Madam,

The Moodle Mobile App cannot connect to the Moodle site: https://moodle.xxxxx.edu even the site address was entered correctly. It keeps showing Loading.

It is strange that only my mobile phone has this problem. The iphone and SamSung Android phones of others can connect to the site successfully.

We have a plan to allow students to submit answer files via Moodle Mobile App during online exam in mid-Dec. Please help to solve this problem.

I am using the model: SamSung Galaxy C5  (SM-C5000)

Android version: 8.0.0

Version: Moodle Mobile 3.9.2

Hello Kelvin,

could you check if you see some certificate warnings when you try to open the site in the mobile browser (Chrome), sometimes there are issues with the server certifies (depending on the Android version they are not always valid)

You can check how good your certificate is by using these tools listed here: https://docs.moodle.org/310/en/Moodle_app_FAQ#I_can_connect_with_my_iPhone_but_not_with_my_Android_phone

www,geocerts.com checked that a valid Root CA certificate could not be located, the certificate will likely display browser warning.

https://www.ssllabs.com checked that there is certificate chain issues - Incomplete. It displays that this server does not support Forward Secrecy with the reference browsers.  It supports TLS1,0 and TLS 1.1.

However, how can I fix the issue of incomplete certificate chain? Please advise. Thank you very much.
