Ciao Graham and John
I have reported the problem, which does not seem to be universal. I am wondering if there is an IP block for a number of failed logins. In a similar situation I have turned off and then turned on again the modem which generally forces a new IP to be issued. Though I have to say that I can find no reference to such a feature in the settings.
I can't devote much time to it today but will get on top of it as soon as possible.
Peter as Graham says enjoy the holidays. I'll reset my modem just in case
