Viber 'Unexpected error'

Hi Guys,
So I was on MinimalOS 2.5 and everything was okay until the last week when Viber FC'd as I tried to make a call. Also I couldn't receive any calls but the text chat worked fine. I did the uninstall/reinstall, clear cache, clear data and nothing worked. Thus I planned to upgrade to MinimalOS 3.0 with Slim Zero Gapps and I did a clean install. Restored the apps using 'Super Backup'. But the viber problem persists! :( I have no idea on what to do.

PS - I'm using viber in this ROM for the last 1 month and nothing unusual like this happened before.

Any help will be appreciated.

Snapchat unexpected server error message solved

Snapchat being one of the high rated social app now a days usually falls in error o sign in issues.
Basically this happens because of your google account not synced with contact details or people details. As per my research and too much of failure i got a successful way to get rid of this problem.
Lets start.
1:- issues can be solved by clearing of cache and dalvic cache of the app. If not solved proceed.
2:- check in settings is your google account synced without error. If sync error remove account and login again.
3:- many of times accounts shows synced but actually its not you can try by remove acc and sigin in again.
4:- Now your google account maybe in condition of can't establish connection. That was the main reason of snapchat not working.
5:- use root Explorer go to etc / hosts remove all lines written and
Edit the lines as followed
127.0.0.1 localhost
#74.125.93.113 android.clients.google.com
Save and exit.
6:- now reboot and login to your google account install snapchat and login you will not face any login error.
Me neither xda are responsible if something happens yo your phone.
