Email been down for the past few hours or more

Task 'XXXXX@YYYYY.plus.com - Receiving' reported error (0x800CCC90) : 'Your incoming (POP3) email server has reported an internal error. If you continue to receive this message, contact your server administrator or Internet service provider (ISP). The server responded: -ERR [SYS/TEMP] Internal error occurred. Refer to server log for more information. [2025-12-16 21:46:51]'

It was running fiine at 18:20 this evening.  Not been able to connect since then.

I've rebooted the PC and the router, but it makes no difference.  

Internet seems to be working fine

Any ideas anyone

Some email has just arrived after 3+ hours of not being able to connect to the server

Included in the emails ... the inevitable phishing stuff ... Norton has been working overtime for the past 6 weeks on my PC !
