Folks,
What do you suggest looking at if the app works when using iOS but not when using Android? We just get the "Oops page". Let me know. Thanks!
Steve
In iOS the app works just fine. We are able to log-in and use things. When we try to use an Android device, we can't even get to the log-in page we just get the "Oops we can't connect page". We do not have a custom/branding version configured for the app. Functionality works fine on the iOS side. Any suggestions?
Hi Stephen,
please, review the FAQ:
Usually is a certificate problem
Juan,
I'm the Moodle admin for moodle.emu.edu and work with Stephen. Could you be more specific about what kind of cert problems cause this issue? For example, is there a specific cipher or protocol option we need to enable/disable? Or something else entirely?
I've run one of the tests and we get an A rating. Problem is it is only testing the cert for our proxy server, not the cert that the Moodle server uses internally. When users are connected to our local network they access our Moodle server directly (so they see the server's cert, not the proxy cert). We've established that the problem does not occur when users are connected from outside our network. So it would seem to be a cert issue with the server itself, not our proxy's cert.
Thanks in advance!
David
Hi Stephen,
try to look at the CAs chained on both the certificates: there are some examples about how to do it, here in the Community e.g. https://moodle.org/mod/forum/discuss.php?d=361822#p1459168 or in the net, e.g. https://langui.sh/2009/03/14/checking-a-remote-certificate-chain-with-openssl/ .
It could be also a problem on the FQDN used vs what issued in the certificate when accessing from inside vs from outside.
HTH,

Hi David,
I'm not really an expert on certificates, I'd suggest you make the internal cert available to Internet so you can run the online checkers and see what they say.
One question, if you try to access your site via the internal network using the Android Chrome browser, do you get any warning in the Android Chrome browser?
Also, Android versions < 4.4.4 have a bug related to certificates (but I suppose this is not your particular case)
