Debug Output/Panic Output

│ Error: updating Network Security Group Association for Subnet: (Name "my-private-subnet" / Virtual Network Name "my-vnet" / Resource Group "my_resource_group"): network.SubnetsClient#CreateOrUpdate: Failure sending request: StatusCode=0 -- Original Error: context deadline exceeded

Expected Behaviour

terraform apply should be working first run also and azurerm_subnet_network_security_group_association should be working.

Actual Behaviour

azurerm_subnet_network_security_group_association running for 30mins and getting timed out, when we re-run terraform it's working. Our actual terraform code is big provided a sample file how it looks like and where are getting errors.

Steps to Reproduce

terraform init terraform plan terraform apply terraform destroy
