Problems connecting to MsSql 2012 server from a remote computer. Where to dig?

Question

Microsoft Azure

Good afternoon.
There was a problem when moving the server, namely:
When trying to connect from a remote machine, error 121 (semaphore timeout) crashes. Through a sniffer it is visible that requests for the server come. The remote studio logs in on the server, then a request comes to it;

DECLARE @edition sysname; 
SET @edition = cast(SERVERPROPERTY(N'EDITION') as sysname); 
select case when @edition = N'SQL Azure' then 2 else 1 end as 'DatabaseEngineType'

It is executed, but the sniffer does not see the response being sent. After that, the cars are thrown with empty packets until the remote connection falls off by timeout.
I forgot to add that in reverse order everything works fine

Answer 1

SQL Azure may limit queries based on its own limits.
Try increasing the size of SQL Azure.
