Unable to connect to servers (non-local)

Hi there folks,

I’m using a Nexus 6 running Marshmallow, and am continually getting errors about not being able to connect to the server. I’ve tried 4G (Project FI) and wireless, but to no avail. Is there anything I’m doing wrong here?

Something wrong elsewhere : [SOLVED] Is Blynk server offline? What about firefighter guy?
