Question

Он отлично работает на местном уровне. Я изменил строку подключения на лазурный db и исправил некоторые ссылки, чтобы получить это далеко.

Answer 1

Я не могу сказать с полной уверенностью, не видя вашу фактическую строку соединения; но, судя по ошибке трассировки стека это означает, что строка подключения использует:

providerName="System.Data.EntityClient" 

попробуйте добавить строку соединения с:

providerName="System.Data.SqlClient" 

Answer 2

Попробуйте отключить пул соединений, установите Pooling=False в строка подключения.
