Error with publishing my ASP.net website - asp.net

Question

solved.
My solution: Build -> clean -> rebuild
I got host for my website and now I'm trying to upload the website's files via VS2017 using 'publish' feature of VS. I setup the connection with the host properly (Validate connection went successful..). But as the VS tries to upload my files it says:
Unable to add 'Content/homePage.css' to the Web site. Unable to parse server response to PASV command.
This error message is shown for each file in my website. The above is just an example to such message. I'm using FTP publish method. My host is 000webhost
