Cloud computing has been made easy with the Azure VM system. Usually, while doing the setup people often ask this question when they are stuck: why can’t I connect to my Azure VM? This happens when your Azure is not working properly because of connectivity issues.
Azure VM connectivity issues can create a lot of chaos. Azure VMs are scalable and on-demand cloud computing resources that help an individual or organization to run their sensitive applications and operating system in the Azure cloud as they are digital operating systems used in the place of physical computers that reduce costs as it is based on pay-per-module and secondly, there is no requirement to maintain physical hardware which automatically provides the flexibility to run sensitive cloud applications and operations.
If your VM is placed in the wrong virtual network then it will show common Azure VM errors that might be disrupting your connection with inbound and outbound traffic as your Azure VM will not be able to access necessary resources. There are several common causes for Azure VMs to not work properly in connectivity while setting up and it can cause your Azure VM to be exposed to unwanted traffic which can also lead to the fixing issues in NSG Rules that are there to filter Azure connection.
Step by Step guide to Fix Azure VM Network Problems and Their Possible Causes
Several common causes can cause Azure VM setup and working failure. It is important to diagnose Azure VM connectivity to solve issues which can range from network to misconfigured settings. This blog will underline the common causes and their solutions for solving Azure VM connectivity issues so that cloud applications and operations can run smoothly.
Configuring Incorrect NSG Rules in the Network Security Group
When Azure VM is used in the NSG group then its inbound and outbound traffic flow is filtered by NSG rules which is why it can be the cause of problems if NSG is blocking the inbound and outbound traffic of Azure VM this will not allow applications to run in cloud.
Solution: Firstly the step that can help in Azure virtual machine troubleshooting is to check the NSG that is attached to your Azure VM network interface and subnet. Once you identify the NSG connected with the Azure VM network then check the functioning of necessary ports are they allowing the inbound traffic or not? If not, then you can add new NSG rules or update rules for permitting allowance to required traffic.
Firewall Settings that are Misconfigured
This Azure VM remote access issue can come in the Azure VM operating system when there is a blockage from the side of the firewall that is blocking the VM access which can be a reasonable cause for Azure VM connectivity.
Solution: You can first check by accessing your Azure VM through the Azure serial console if it still doesn’t work then checking from other remote tools can come in handy. After accessing Azure VM the next step you can take is to set the OS firewall settings to allow traffic flow on your required ports this will resolve the blockage.
When VM Stopped Working or Got Delocated
One of the major causes of Azure VM failure is delocation. But by resolving Azure VM public IP issues this problem can be solved with ease allowing the VM to work properly again.
Solution: Starting the VM from the Azure portal or by using CLI can be the first step to resolve this issue once it is started make sure to verify the VM’s public IP address because there is a chance that the previous public IP address would have changed due to the restarting process.
Causing Troubles due to Virtual Network or Subnet Issues
VM connectivity is very important to establish a connection but sometimes when the VNets and subnets get misconfigured it can block Azure VM connectivity which can hinder your application and operation run on cloud.
Solution: This is one of the important steps to troubleshoot Azure VM network issues as VNets and subnets access allows the traffic flow and if it is blocked your Azure VM will not be able to build connectivity. To make sure your virtual network is working fine first validate access from VNet and subnet settings. It is important to ensure after validation that your subnets are allowing traffic to your internet and VNets if it is necessary because, without this validation and allowance, the blockage will not open.
Conclusion
Azure VM connectivity issues can arise suddenly and it can be there due to several causes. But what is more important is one should know how to fix Azure virtual machine connectivity problems so that your business can attain seamless working efficiency on the cloud and also it ensures the Azure VM working remains operational smoothly.
