Issue configuring secundaries "Ip Configurations" on a Network Interface

I am experiencing some problems when trying to create secundaries ip configurations for a network interface. I need to configure secundaries ip configurations with public accesible ip but, despite configuring the ips, they are not accessible most of the time. Only when I update the ip configuration, the configuration seems to be applied(For example, change the public ip to another and then change it back to the same).

I have tried to do it through the azure portal gui (selecting my network interface/settings/Ip configurations) and through the az command line and in both cases I get the same issue.

Example command:

az network nic ip-config create --name configuration-ip-name --nic-name nic-name --private-ip-address 10.0.1.11 -ID -g group-name

Hello @ZevenetSL-4946 ,

Could you please provide some more context on your issue? Are you adding a secondary Private IP or Public IP to your NIC?
If you are using Private IP and unable to access Internet, you could refer the below:

Thanks,

Hello Gitarani, thanks your for your help.

I am trying to configure a secondary Public IP related to a Private IP. My VM is able to access the Internet, so this is fine. I am a http service listening on this secondary public IP but, for some reason, after delete and create the same configuration, the service don't response to requests. Only when I update it(for example: reconfigure ip), changes seems to be applied.

My VM is running with linux debian.
