I'm set up for SSO and it works just fine for the RC Desktop (PC) and RC Meetings application (PC). Up until last week, it was working just fine on my RC application (Android) but I now receive a webpage cannot be displayed error after entering my email address associated with my SSO enabled RC tenant.

The RC Meetings application (Android) works just fine.

I can reproduce this issue on multiple Android devices and multiple user accounts.

Has anyone come across this issue?

Thanks in advance,
Elvis

Two suggestions: Did you already un-install the app from your Android once and re-install it?    In your Google settings, they may have the app listed as "less safe" ----   you can override that by allowing "less safe" app and then restart the phone, to allow the authentication routine to try again using your SSO credentials.

Thanks Cecile - Yes, already tried uninstall/reinstall multiple times. I'm using my on premise ADFS, not Google as my SSO credential source. .. It's indeed a strange issue.

Android devices all look to the Google Play Services ecosystem for various token passthroughs - it may still be a Google setting that is prohibiting the credential passthrough on your own premise based SSO system - I would still look in your Google Logs to verify that it is not prohibiting the passthrough

EPalombiziom, 

Did you resolve this yet?  If not, reply back here and I'll open a case to get this escalated.

I haven't. I have a case open with RC Tier 2 as I'm able to reproduce the issue on Apple devices as well. I have a feeling the issue lies with a particular endpoint URL on my ADFS and RingCentral. I'm not sure why all of a sudden it's a problem, but I was able to replicate the issue with the GLIP application as well. I'll post my outcome to this forum in case it helps any future users.

Thanks for asking,
Elvis

It looks like the Tier 2 agent tried to call you and left a message.  If there's good time and number to reach you please reply to the case:

Just an update on this. RC is still working on it. We've been over the SSO settings multiple times but there are no smoking guns on my end. The one oddity is that the RC mobile app fails to use SSO properly, but the RC Meetings mobile app does.. I'm hoping RC can shed light as to how these two apps leverage SSO differently to help narrow this down.

EPalombizio,  I see the case is still open, but there is activity on our end. I'll try to get you an update ASAP.

Mike - thanks for taking an interest in this case. The pace of troubleshooting of this has been painfully slow to me.

My first issue is the lack of interactive dialog on this issue. I submit an answer, receive another question a day or two later, repeat the cycle. Having an interactive support session would help immensely.

My second issue is that to help RC troubleshoot this, I need to understand the difference in how SSO is used between the RC Mobile application, the RC Meetings mobile application, and the RC Windows desktop app. The RC Mobile application fails to authenticate, but the RC Meetings and RC Windows desktop app authenticate just fine using SSO... If RC can tell me what the differences are in authentication mechanisms used for each of these apps, I could help narrow down the search and help figure this out on my end.

Having SSO working properly is very important to the potential deployment of UC services. The fact that this worked just fine for months and now has become a problem makes it even more frustrating.

Thanks,
Elvis

I received an update a moment ago from support indicating they believe it might be an issue with basic authorization with embedded browsers on mobile devices.

I'm using ADFS hosted on my end. Does anyone out there have a similar setup, and if so, are you experiencing the same issue?
