Error gathering analytics data from Google

In Google Developer Console it is said that I haven’t exceeded the quote at all — https://gyazo.com/c7e82b9628fdb290dab21d49a24161f0

I have even tried adding this code in my functions.php

add_action( 'admin_init', 'delete_gad_options' );
function delete_gad_options() {
	delete_option( 'gad_login_pass' );
	delete_option( 'gad_login_email' );
	delete_option( 'gad_auth_token' );
}

But after reauthenticate I recive the size problem again.

I would highly appriciate if you could share any advice as that plugin is very important to me as it shows amout of visits near each post in wordpress and that is very helpful for my authors to understand what is popular and what is not.

Recently I have moved to another hosting with NGINX. Probably the problem is somehow related to it.

Please help.

I also have ngx_pagespeed module and fastcgi_cache_purge module intalled for Nginx. Do you think those can reflect on the plugin?
