POP3 server not responding for incoming emails....

[Flowertop]

Hi, this will probably very easy but for me I have no idea. I have been using email all day fine and then I have an error message come up when I try to receive emails. The message reads:

Log onto incoming mail server (POP3): The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP). The server responded: -ERR Cannot connect to POP server 212.74.100.190 (212.74.100.190:110), connect error 1006.

I can send emails but not receive. Grateful for any help you can give.
