We have a client that have an Portal installation and Esri apps for the field work (Survey123, Workforce, Collector)
In short: Survey123 does not log in when using a local certificate authority certificate but works fine when using a public certificate:
- Client’s GIS and Planning Unit server is back facing and not public facing
- Due to the above they require security certificates to allow for communication between the 3 apps we use (Workforce, Survey123 and Collector) and our ArcGIS Portal
- Initially they had these deployed on Lenovo Tab4 8’s (Tab 4 8 | A Premium 8” Tablet for the Whole Family | Lenovo South Africa ) which initially had Android 6.6 – The apps ran perfectly
- They then did an OS update on the tablets to Android 7.1.1
- Unknown to them, Android 7 has new security protocols that do not read user uploaded certificates
- This then caused SSL handshake errors between the apps and our portal
Does anyone know how to work around this problem?
