After updating, my POP3 will not authenticate, nothing has changed except updating to latest. I logged in to gmail in a browser with the same credentials no problem. Here is the error in the logs: /usr/local/lib/ruby/2.5.0/net/pop.rb:1006:in `check_response_auth' /usr/local/lib/ruby/2.5.0/net/pop.r…

Same issue. It started this morning on my one week-old Discourse version, so it’s not a change in Discourse, but something that Google did. Like @davidkingham I have " Less secure app access " enabled and I can log in to Gmail via browser with existing credentials. [52%20AM]

That worked, @itsbhanusharma - thanks. In case this is something others encounter, to switch to an application password see: https://support.google.com/accounts/answer/185833?hl=en

Gmail is trying to be more secure. Unless you have specific reasons to poll gmail, maybe consider running the mail-reciever container to handle incoming emails.

This worked for me as well, FYI for others when creating the key; under the app dropdown, select ‘other’, not mail. Thank you @itsbhanusharma

Maybe try using Application Password instead of regular password?
