Hi Blagoje Ivanovic,
Welcome to the Microsoft Q&A Platform. Thank you for posting your query here
Based on your query, I understand your concern. Can you go to directly virtual network section separately in portal and able see what you have created vnets is that present? and also try using Azure CLI a try to check if the VNet IP and other details are reflected there use below commands
az network public-ip list --resource-group <resourcegroup> --query "[].{Name:name, PublicIP:ipAddress}" --output table
az network nic list --resource-group <resourcegroup> --query "[].{Name:name, PrivateIP:ipConfigurations[].privateIPAddress}" --output table
az network vnet list --resource-group <resourcegroup> --output table
az network vnet subnet list --resource-group <resourcegroup> --vnet-name <vnet> --output table
For more information on commands, please refer below document
az network vnet
az network public-ip
az network nic list
az network nic
After trying these steps, please let us know if the network interface IP and other details are showing up. If all the IPs are visible, then there might be an issue with the Azure portal UI interface
Please let us know if you need any other information tag us in comment, we will help you further as you needed!
