Gmail or Inbox not loading mails

I'm using gmail and inbox in my browser, they just work fine. However, on Android the Gmail app or Inbox app both displays nothing left whereas I do have emails in my inbox. If I try to switch in other categories such as spams or trash, it displays "No network" even though I'm connected.

I have a rooted phone with JB 4.2.2 (deodexed) and:

• Xposed


• Greenify Pro


• GravityBox


• Xprivacy (not for system apps)


• ...


• I removed some system apps using ROM Toolbox but only samsung's bloat

I tried:

• turning off Greenify auto-hibernate and Xprivacy for inbox


• deleting data of Gmail, Inbox, or Google Play Services. When I try to use Inbox it now asks me to connect and then says that an error occured and try again later.


• download manager is not disabled


• removed /system/etc/hosts
