Hi,
I would like you to test the firewall connections are well configured. Following steps would help
export IpStart="0.0.0.0"
export IpEnd="0.0.0.0"
echo "Firewall rule for starting ip of $IpStart" and ending ip of $IpEndaz
sql server firewall-rule create --server $server --resource-group $resourceGroup --name AllowYourIp --start-ip-address $IpStart --end-ip-address $IpEnd
Above settings is for opening the firewall to allow access from anywhere. It is unsafe for production environments and here we are just trying to isolate the issue
