11.38 POP login issues?

[bear]

Anyone else seeing POP login issues since the update to 11.38? I have one client that keeps being asked for his password on several devices (desktop, ipad, iphone) and is having trouble staying connected for email. I can't reproduce it, and have only heard from this one client on the box, so I can't say for sure if it's everyone (he uses email quite a lot more than anyone else on there, so notices immediately when it's not working properly). I do know I can connect to a POP on that box without issue, so it seems like just him so far.

It started with the upgrade to 11.38, so I'd like to rule that out as a cause if possible.

This one user is also unable to log into Cpanel, apparently, giving an "invalid user/pass" error. Given his info, I was able to log right in without issue, as was someone else he knows. Only he can't. He's not blocked in any firewall, as he can get to his site and the cpanel login.
Weird.

Hello

Have you checked to see if the email account was restricted by cPHulk brute force detection? You can review the Login/Brute History Report at:

"WHM Home » Security Center » cPHulk Brute Force Protection"

Thank you.

ok, it was just him. Feel free to disregard, it was something to do with his local systems, and is working once more.

The Admin’s Toolbox, Vol. 1 – tcpdump and you. | cPanel Blog might be worth a read to get an idea of what actually is coming down the wire on his sessions...

Admin toolbox; bloody helpful, that. Thanks, Thinice (and you, too Michael!).

Yeah, it's a pity that more blog articles in that series don't appear to have been posted. That said the general documentation is in general much improved over what it was

Maybe you have setup the limit of maximum number of connections from a particular IP too low?
