I’m uploading custom wordpress theme files from a mac to a remote server. I am using SFTP with Cyberduck, transferring a variety of file types (php, css, less, png, jpg, gif; typical website files) from my local machine to a remote host, and random files return a 503 error once they’re uploaded.
I’ve tried deleting the files returning the error, and then re-uploading using a different client, that doesn’t work. I refresh the remote files list in either of my two FTP clients, and the files are there. I refresh the web page in the browser after waiting to see if it’s just that the server is busy… nothing. Same error.
It seems random CSS and image files are returning a 503 error on the server, and I have no idea how to fix this. Any ideas?
Suggest you upload those files separately. Will it be that uploading to fast because your css/images file are too small such that the ftp server is too busy to deal with the requests?
