Thunderbird stopped sending and receiving a week ago.

SuMo Bot

My wife lost the ability to send or receive email with Thunderbird on her computer a week ago. Other users in our house have no problem with different email apps on different servers. In addition, my wife is able to access the ISP's mail server and send and receive messages with that tool. Only Thunderbird is failing. The ISP confirms that Thunderbird is pointing to the ISP's correct send and receive mail servers. When she tries to send a message, it says "sending" and then hangs. When she has selected "Get all new messages", it has timed out after about a minute. Today, when she tries that, she gets a message that I haven't seen before: "The operation timed out when attempting to contact live.thunderbird.net". I don't understand why an attempt to update her inbox should induce a communication with a Thunderbird server. Thunderbird should only be talking to the ISP mail servers. Is her DNS corrupted? If so, how do I fix it? Thanks very much.

More information is needed, such as her email provider, such as AOL, Gmail, etc. Plus incoming and outgoing server settings. Screenshots of actual server settings are preferred. Also, what version of Thunderbird. What OS? WIndows? Linux?
