I just signed up at Libera Folio and it asked for my retadreso and I typed the URL to my YouTube account. It gave an error and I then realized that it wanted my e-mail address.
I learned retpoŝtadreso for e-mail address. I have been under the (apparently wrong) impression that retadreso meant URL.
Which one should I use? Does retadreso always, in all cases, mean e-mail address?

No, your impression is not apparently wrong. Retadreso does mean URL but often retpoŝtadreso is shortened to retadreso, which IMHO is a bad practice.
For e-mail address, PIV gives the simpler word retadreso (which is, however, used for web address), while other sources prefer the unambiguous retpoŝtadreso. As usual, this info comes from Komputeko.net.
And I see you have already been given the translation of URL: Kiel oni diras "URL" esperante?
