K9 mail on phone sends fine, on tablet no go

I have an LG phone (Volt 2) and an LG Tablet (G Pad 8.3). I use K9 mail for my gmail and pop accounts on both devices.
I have no problem at all sending mail from phone but constantly get a "mail not sent" or "cannot connect to server" on the tablet.

I have checked over and over that the settings on the phone are exactly the same as the ones on the tablet yet one works, the other doesn't. For both devices I am using smtp.gmail.com as the SMTP server.

Really could use a smart person to step up and tell me why that's happening and whether it is fixable.

Thanks,

Unfortunately yes, the SMTP server is set correctly, the security setting on both the phone and tablet read SSL/TLS and the port is 465. I've entered the password numerous times on both devices but the tablet won't connect to the server. Weird, puzzling, and frustrating.

 

I checked and both phone and tablet show "Normal password."
Have had both the phone and the tablet for about a year. Tablet has sporadically shown the error message but now routinely does. Interesting note is that I sent a test message out a few hours ago and got the error message yet a few hours after that the email made it to the desired box on my PC.

Tomorrow I may give it a shot with the Force Stop. Thanks for the thoughts on the matter.

 

That may be the case but in this case K9 mail does fine with both my POP server and Gmail on the LG Phone and on the tablet and only has an issue with the SMTP of Gmail when trying to send mail from the tablet.
I'm thinking of switching to using the SMTP server from the POP ISP rather than from Gmail for sending out mail from the tablet.
