Well, it was a stab in the dark… mostly based on the fact that that same error was referred to for another reason (too many projects).
Further Googling located this github reference to all the Android error strings… which cryptically says you aren’t allowed 
<string name="error_user_not_allowed">User not allowed to perform this operation</string>
We will have to await more informed assistance

Local Server can be ran on just about anything that can run Java… even the computer you are currently using.
Here is another Local Server link that might be more useful (I really wish Blynk would put all these tutorials in ONE spot).
