Comoda's False positive submit page is down. can not submit and upload file

our company’s legit software is false postive flaged by comodo, tried above link to submit , but never worked.
always saying upload file failed. tried many times already and tried from using different network connection.

plz fix it. i have attached the screen shortcut.

btw, its not the file size issue. our file its only 1.5MB, and i tried to submit a 1kb text file as well, always the same error notification “file upload failed”
