I tried FileZilla and received and FTP error 530 re authorization. It appears there is some problem with my password. The best part is when I attempted to change my WU password, WU never sent the reset email. Tried several times. The best part is that they don't respond to emails. So for now it's time to put this experiment aside. Thanks for the help.
If it makes you feel any better, I had the same problem. Today, in an effort to help, I reset my old WU password from circa 2007 and created a PWS (weather station) to upload data from my Davis Vantage Vue. It may take some time for it to show up, they said.
While waiting I decided to upload my flag cam, using the supplied FTP server name, user, pass, etc. ...you know the drill...no joy, got 530 like you. Checked and re-checked...no better. So I break out Filezilla and tried to upload an image. Same results...got a 530. Suffice it to say I have FTP'd literally hundreds of times to about a dozen different websites, including 3 of my own all on 3 different hosting companies with NO ISSUES WHATSOEVER, AND AT NO TIME.
As
@looney2ns said ( in so many words) ..."Dey got sum issues, man."
