Dear people from Macrumors, Sorry for posting a problem as a first post but I'm about to throw my Macbook thru the window at the moment. My problem is the following: I can't open the website of one of my clients. Since I have 2 email accounts at this website I'm also unable to receive mail. I have listed a few conclussions so hopefully someone knows exactly what the problem is. - I can't open the website or any website that's related to it on my macbook pro using several different wifi networks. - I can't open the websites on my phone on a wifi network. - I can't receive any emails from the address on my macbook - I can open the websites on my phone on a 3G network. - I can receive emails on my phone when not connected to wifi - I can open the websites using www.hidden.cc (a proxy) I tried flushing my cache using dscacheutil -flushcache but this doesn't help me. My client didn't block me somehow I hope someone here can help me. Thanks a million in advance!!
