Macbook air wont connect to octoprint

everything else connects to my pi, mac mini, my phone, my macbook air did until yesterday

safari cant open because server where this page is located isn't responding

ive tried safari and chrome still the same only on this air, also tried it on sky router and iphone personal hotspot

What did you enter into the address bar? http://octopi.local? Try the ip instead for example http://123.456.789.123

That’s what I do use the ip address, the ip address works on my phone and on Mac mini, just not on the MacBook Air, it did work, just stopped yesterday for som reason
