If the problem persists, you may consider a VPN, which will make your traffic invisible to whatever is blocking whatever is causing the problem. It does cost in time: the additional routing will slow down your connection. I believe there are free VPN hosts out there, but it's not a subject that I am really familiar with.
Another possibility is changing to a different DNS provider, which is just a configuration change. That could be part of the problem, and this is definitely free.
It is also possible that there are specific terms in your landlord/tenant lease, or whatever they might call it there (I think it translates to bangers & mash :-) ) that would be violated if you used a VPN or changed to a different DNS provider.
