Hi all, I had been using the email-in and reply-by-email features and they were working well for a few months until they suddenly stopped working. I suspected that the polling period was too frequent and google may have blocked my install. I reset the email settings, created a new google apps emai…

Here’s how I would debug it: SSH into your server and then cd /var/discourse ./launcher enter app rails c require "net/pop" pop3 = Net::POP3.new("pop.gmail.com", 995) pop3.enable_ssl pop3.auth_only("username", "password") And check what error you get from the last line.

root@localhost-app:/# rails c You are running an old version of bundler, please upgrade bundler ASAP, if you are using Discourse docker, rebuild your container. [1] pry(main)> require "net/pop" => false [2] pry(main)> require "net/pop" => false [3] pry(main)> pop3 = Net::POP3.new("pop.gmail.com", 99…

@brianmcdonald , I realize you may not have the same setup, but I too had a situation when the setup looks good, but on re-click “pop3 polling enabled” it gives the “POP3 authentication failed” error. I have a https only site setup with Google Authentication working on a different machine a few day…

Hello, I’m running into this issue too. I did the diagnostics recommended above and got this error: [изображение] I’m a little bit lost - does that have something to do with the gmail configuration, or something on our server?

Please make sure you update to latest. This bug was fixed last week.

@gerhard currently running 2.4.0.beta4 which the admin says is latest. Is there another update?

Go to /admin/upgrade to update to latest.
