According to your description and codes, I think it may be caused by a permission problem, please try to give the corresponding permissions to the Upload folder. Such as the following.
In addition, I am not clear about your web server environment. It seems your code doesn’t have any problems. Could you please post more details about your problem? such as, how did you see that the file was not uploaded, and the upload code was executed
correctly? Could you please tell me about your IIS environment?
Look forward to your reply.
