So What I’m doing is creating an excel file using epplus and saving it to response.outputstream
For some reason the code breaks giving me an error. I have no idea what I’m doing wrong.

I get this error
0x800a139e – Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.
You probably call this from UpdatePanel, or from Ajax call – but there what you do it to clear the response header and instead of json that ajax wait for return, you send something different (here is an xlsx file) – and you get that message, that can not parse that excel.
The ajax or the UpdatePanel can not understand that you try to send something different like this file. What you must do is to create ether handler that send this file, and place it in a hyperlink, ether remove the UpdatePanel.
