Using Webclient to consume Azure Function App URL Data

Hi,

I am using webclient.downloadstring C# to fetch the azure function app URL data.

webclient is not working properly and sometimes I get the 404 not found error and some days it works fine without any changes.

I am not sure what is really wrong . Please let me know how can i fix this ?

@Uma Devi Ananthu Vidhyasagar Thanks for reaching out. If you are getting a 404 not found error when using WebClient to fetch data from an Azure Function App URL, it could be due to a few different reasons.

Make sure that the URL you are using is correct and that it points to the correct Azure Function App that is in running state.

can you try using a different method, such as HttpClient, to fetch data from the Azure Function App URL to see if the issue is with the WebClient class.

please try and let me know if this helps!

@Uma Devi Ananthu Vidhyasagar If you are getting the same problem with HttpClient as well, then the issue is likely not related to the specific method that you are using to download the data. Instead, it could be caused by a network issue, a problem with the function app, or an issue with the URL itself.

Try accessing the URL directly in a web browser to see if you get the same error also check Azure Functions diagnostics it is an intelligent and interactive experience to help you troubleshoot your function app with no configuration or extra cost. When you do run into issues with your function app, Azure Functions diagnostics points out what’s wrong.

do check and let me know if it helps!
