I'm on a corporate network with various mysterious lockdowns including ZScaler
My current issue is that when I try to connect to xyz.databases.windows.net (Azure SQL database) I see these symptoms:
From SSMS I get
No such host is known
Trying nslookup
nslookup xyz.databases.windows.net
Server: abc.au.mydomain.com
Address: 10.x.x.x
Non-authoritative answer:
Name: xyz.database.windows.net
(note no IP address returned)
If I switch to a different non-corporate network I can connect fine.
I'm about to raise a ticket with the sausage factory to try and resolve but would appreciate some insight on what's going on here so I can discuss with a bit less ignorance. NSLookup doesn't return an IP address. Does that mean the DNS server is actively blocking this? Or something is misconfigured somewhere?
There is some info in server side setup here, but this seems like a client side issue.

nslookup xyz.database.windows.net 10.x.x.y
database.windows.net
in the list?
