Unable to establish TLS connection to POP3 server.
I can receive emails on my phone with my domain, but on my PC suddenly I started getting the following:
Unable to establish TLS connection to POP3 server. The server may be down or may be incorrectly configured. Please verify the correct configuration in the Server Settings for your mail server in the Account Settings window and try again.
It happened suddenly and i am sure i haven't changed any configurations. Can anybody tell me what's wrong Thank you Mark

Try again later. You may also check with your email provider whether they are having a server problem.
It has been down for three days now, I can receive emails on my phone from the same provider.
Please post your Troubleshooting Information.
At the top right of the Thunderbird window, click the menu button 
, then select Help > Troubleshooting Information.
Press the "Copy text to clipboard button" and paste the information into your reply.

Your server setting for the incoming server looks a bit odd. Whether this is correct or not I don't know. You should check with your email provider about the correct settings and adjust them in Thunderbird if needed. Things can change on the server side over time, and not all email providers give notice and instructions in advance.
Antivirus: Norton 360
Anti-virus software often causes problems with Thunderbird. Try to start Windows in safe mode with networking enabled. This will temporarily disable anti-virus software. - Win10 https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode
Does the problem go away?
ukservers.net redirects to names.co.uk, and their instructions for POP mail accounts in TB recommend pop3.names.co.uk on port 995, SSL/TLS, authentication = normal password, User Name = email address. Outgoing is smtp.names.co.uk on port 465, other settings the same as incoming.
Agree with previous post re Norton: disable any options to scan mail folders or secure connections.
