Hangouts: Cannot Connect to Server After Update Recently, Google released a fairly major update to Hangouts, an instant messaging app as well as an alternate SMS client. I have a phone (model is irrelevant) and a Nexus 10. I updated to the latest hangouts on both devices. 

On the phone, it works great. On my Nexus 10 however I get a 'Cannot Connect to Server' Error when starting the app:

It is odd because if I click on a notification of a message it will go straight to the conversation and not cause any issues. The main issue seems to happen when signing in to the main page:

To be clear, I still get notifications about messages, but I cannot open them in the app: 

My Nexus 10 is running android 5.0.2 on the RemixOS ROM. I have tried going to stock android 5.1.1, wiping cache, user data and dalvik cache all to no avail.
Does anyone have a fix to this problem? If not, are there any good Google Voice clients?
I have had an issue like this with a past update on Hangouts and fixed it by updating my "Google Play Services".
Other things I tried that may have inadvertently helped was restarting and connected to WiFi.
