Android client show and error after press "Continue" button: "An error ocurred while connecting to the server"Answered
I have Android v5.0.2 and Rainbow v1.66.3.
I have installed the application for the first time. After pressing the "Continue" button, the message "An error occurred while connecting to the server" is displayed at the bottom and does not allow me to enter my account password.
What could be the cause of the error? In the mobile I have no firewall or anything similar.
The root certificate of these old samsung devices is not valid anymore. That's why it is not possible to connect to Rainbow servers.
You must install a new root certificate manually on the smartphone by downloading it here:
Hello, the same day that I could not connect with my mobile, I did a test with another mobile from my same network and with my user. The other mobile, with Android 6.0, connected without problems right away. This "correct" connection is what you should have seen, but with Android 5.0.2 I still can't connect.
Anyway, do not worry, seeing that the problem seems to be that you indicate that you need Android 5.0 minimum and actually it seems that you need 6.0, I will buy a new mobile with a higher version of Android and problem solved.
Thank you very much for checking and interested in my problem.
I have the same problem.
I have a Samsung Win Duos running Android 5.0 and I get the same error message when I enter my email.
I would really like to know if the minimum version of Android needs to be 5.0 or 6.0?
Can installing this certificate cause any collateral damage to the device?
Thanks in advance,
The minimum version is 5.0. As Claire says, the problem only occurs on older Samsung phones that don't receive root certificate updates.
By accepting an external root certificate the Android security system forces you to have to define a pattern or lock system to access the mobile, you can not just slide to unlock. I already had a blocking pattern defined and it did not represent a problem for me.
In the end I bought a new phone and I no longer have this problem, but I managed to get my old phone to work for a while with Claire's instructions.
