Azure File Storage the server responded with a status of 400 (Condition headers are not supported.)
I have some png files stored in Azure file Storage, and I'm retrieving and displaying it from my MVC web project to the browser. But sometimes I get the below error message from browser console.
Failed to load resource: the server responded with a status of 400 (Condition headers are not supported.)
If I refresh the page again, the error message disappears automatically. But it doesn't solve my problem as I run my MVC project again, the same error comes back. How to solve it?
It's acutally a common issue on Azure Storage, which be listed in the offical reference Common REST API Error Codes as the figure below.
It means that Get File REST API does not support those request headers which not be listed in the Request Headers.
There is a similar SO thread Azure File Storage Error: Condition Headers Are Not Supported, which got the same issue with yours. It seems to show up different behavior in different browses when you get a file from Azure File Storage.
I could not reproduce this issus by a file url with SAS token, but I really recommend that you need to store these static files like images on Azure Blob Storage, as I known and as Azure best practice, to show an image by its url with sas token or a public container.
