Can login via browser, but all other clients fail on authentication

[FaithPerring]

Recently found that my Em client software was failing to connect with authentication error. Also my Ipad email was failing to authenticate, but I could login via the web browser to view my email.

I changed the password via the browser, but the other clients still failed.

I asked a friend for help and they installed and tried Thunderbird on my PC, with the same issue.

They then tried Thunderbird on my Android phone, same issue.

There is obviously something, a setting at the Talk Talk end that only allows my mailbox to be accessed via a browser and not a client. Can this be corrected please.

I am 100% confident all the settings used are correct.

I have updated the profile as requested.
