I\'m trying to upload a image in Windows Azure Blob and I\'m geting the following error which I can\'t handle.
Server failed to authenticate the request.
ERROR MESSAGE
Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.
SOLUTION
I was facing the same issue in my application and i resovled it by generating a shared access signature (in azure portal) for key2 instead of key1. Changing the key fixed the error. (Settings > Shared access signature) Also keep in mind that the connection string should be updated as well - if used. (Settings > Access keys)
