I use eM Client to retrieve email from Hover (mail.hover.com) via POP, and the last time it was successful was three days ago (on June 13 2026). Since then, each time I start eM Client, the progress bar starts to slowly grow, and I see what looks like dozens of messages getting downloaded (and added to the Inbox and Unread count), but my guess is that they are very old, since they don’t appear at the top of the inbox; and then an error pops up:
[POP3] Can’t retrieve POP3 message due to the following reason:
“”
What does an empty string reason suggest might be failing here? …I vaguely recall recently installing an update to eM Client (on my Windows 11 PC), but I can’t recall if it was after that last successful download.
