Website being blocked

[#1]

Hi, I cannot access https://gozumbauk.com/ from the Plusnet router. I can access it fine over a data connection and the website is defiantly working for others. I've checked with friends and those on Plusnet cannot connect to it either. Does anyone know how I can resolve this problem please?

Thanks, Tracey

If you had your own router you could amend the DNS settings, but with PN's supplied one, these are locked.

Sadly that's not an option...
