SQL Azure database connection issue

Question

My problem is, I am getting below error when I try to connect the SQL Azure database by using SQL authentication from the Azure VM. The problem is interesting because I can connect same database from different Azure VM. SQL Server has a firewall and both VM IP addresses are whitelisted. I tried to make tcpping to SQL destination from both VM works fine. Unfortunately, I don't have access to grab the azure diagnostic log from the destination SQL Server. Does anyone have any clue what could be the problem?

Error message:

Cannot open server "XXXXXX" requested by the login. The login failed.

Congratulations that you resolved the issue:

"Yes, I was able to resolve the issue by moving VM to another vnet. It was using private IP even though it has public IP, I believe because of subnet service endpoint configuration"
