We are looking to start using the moodle mobile app within our organisation however we keep recieveing the below error when trying to login using both IOS and Andriod devices.
We are currently using moodle version 3.4.2 (Build: 20180319)
We are running an SSL certificate issued by Let's Encrypt Authority X3
We have used the moodle mobile app in the past with previous versions of moodle with no problem so we are not sure what we are doing wrong here. The setting "Enable web services for mobile devices" is enabled. We have followed all published information to get this working any guidance that you could provide would be helpful.
