We have deployed ArcGIS Enterprise 10.6.1 into a customer site, along with Enterprise there is a separate machine running a Portal Web Adaptor.
However when trying to connect to Survey123 in Enterprise using an Android device users are receiving a "SSL handshake failed (6) error. It appears that it might be some sort of certificate issue. The customer has a valid COMODO issued certificate and there is no issue when connecting via an iOS device. We have checked that the certificates have been imported into the various servers, all appears to be correct. Have also updated to the latest version of the app (3.0.149) Is there anything else to check? Any assistance or ideas appreciated.
