Talktalk webmail has been working fine until today. Now whenever I try to connect to apps.talktalk.co.uk in order to login to webmail on my PC, I get an error message regardless of browser (Chrome, Edge and Firefox). See example of Firefox browser message below. However, I am still able to using Safari browser on iPhone. Is there an issue with the website certificate for PC access as Firefox implies?
