Firewall does not allow access to this server from current IP address
Published 18 January 2018
Problem:
Cannot open ‘SERVER’ requested by the login. Client with current IP address is not allowed to access the server.
Solution:
To enable access, use the Windows Azure Management Portal or run sp_set_firewall_rule on the master database to create a firewall rule for this IP address or address range. It may take up to five minutes for this change to take effect. Check out this MSDN article article to learn more.
