Unable to write data to POP3 server pop.gmail.com on port 995

I’ve tried many variations of cURL vs. Sockets, tried imap and pop3-ssl. No settings work. I’d really like to buy the category by user add on, but I’ve got to get this working at a basic level first. I use WP Engine for hosting, but they said they didn’t block use of port 995. I’ve seen other posts here that contradict that statement, but I’m not sure what is the current information. Here’s the Test Config results. Help appreciated!
