File Uploads

Hi

If I am able to upload any type of document to a site other than a .xls file. I tried different sizes and it didnt work, when i try xlsx or word documents, no issues

Could something within the F5 configuration be stopping the file from uploading. I have ASM installed but it is set to Transparent at the moment. I also dont see any errors with TCP traces all i see are response code 200 and 304.
