We must configure the right TLS on an Azure web application and on our security service (in my case I am using Cloudflare) if it is not configured properly, then we will get the below error. For application security testing, make sure you are using Internet Explorer or Microsoft Edge.
This might be because the site uses outdated or unsafe TLS security settings. If this keeps happening, try contacting the website's owner.
In order to resolve this issue, you must follow the below steps.
Step 1: Check your system's internet options on your local system.
Step 2: If you're still facing the same issue, check TLS settings on the azure web app.
Step 3: Check TLS settings on your middle-security service (in my case I am using Cloudflare). It should match with Azure TLS or a lower version.
Refresh your browser, and make sure your app is running properly.
Keep enjoying the secure app!
