5 Ways to Fix Azure Web App Crashing

Like any other web app, Azure sometimes experiences crashes, freezes, and bugs. There are many potential causes behind such issues. Fortunately, there are also plenty of quick fixes you can try to restore full functionality and get back to work on your Azure app creations.

Here’s how to fix Azure app crashing.

Method 1. Restart the App

Sometimes, the simplest fixes are the most efficient, and something as simple as restarting the app could be enough to fix Azure app crashing. You can do this within the Azure portal itself, so there’s no need to actually close it down.

Step 1. Look along the Azure app blade and find the “Restart” button. Click that. If it doesn’t work, you can press the “Stop” button first, then try “Restart.”

Step 2. If this method doesn’t work because of how Azure is frozen or crashed, you can just close the entire app window and then reload it.

Method 2. Adjust Your Pricing Tier

Many instances of Azure web app crashes happen because you just don’t have access to the resources needed to keep your app running. This can occur when you’re starting to scale up your project or add new features and dimensions but don’t have an appropriate Azure service plan to match.

Step 1. Open up the Azure portal in your browser.

Step 2. Look for the “Scale up (App Service plan)” button in the App Service app page sidebar and click on it.

Step 3. Choose one of the pricing plans with additional resources (more memory or CPU cores, for example. Press the “Select” button. You’ll see a green check mark notification.

Step 4. Return to your project and carry on working. If it crashes again, you may need to go back into the service plan menu and pick one with even more resources.

Method 3. Scale Up Other Resources

You may have projects that draw resources from other services, like Azure Storage or the Azure SQL Database. You might need to scale those up accordingly to fix Azure app crashing. Here’s how:

Step 1. Go to your app’s “Overview” page and select “Resource group.”

Step 2. On the overview page of the resource groups, pick the individual resource you want to scale and follow the on-screen prompts. The exact process will vary, depending on which resources you’re working with and where they’re coming from.

Method 4. Disable Health Check

Some Azure users have found that switching off the “Health Check” feature for their apps can fix sudden crashes. It’s not known exactly why, but it’s possible that the Health Check process can cause some interference with other elements of Azure.

Step 1. Go to the Azure portal and pick the app you want to work with.

Step 2. Find the “Monitoring” tab and then look for “Health Check.” Click to disable it.

Method 5. Use the Diagnostic Tool

Azure also has a built-in diagnostic tool you can use at any time to check for issues and, ideally, have them fixed for you automatically.

Step 1. Open the App Service of the Azure web portal.

Step 2. Click the “Diagnose and solve problems” button in the sidebar on the left. Wait for it to finish scanning and fixing whatever issues it can find.
