Websites take really long to load under some network

For some reason, all pages under hyper.land take at least 1 minute and upward of 10 minute to load. This is while duing my laptop is connected to my local network but with mobile service the website works fine. Both of these internet came from the same provider.

What can I do to resolve this? Should I contact my provider?

they load instantly for me, so it might be a problem on your end.
