Disabling Privacy Preserving Ad Measurement in Safari to resolve 'Server cannot be found' error
A lot of people have had this issue and no answer has helped but I figured it out and wanted to make sure I shared so no one else would have to search and never find the answer.
Go to “Settings”, “Safari”, scroll all the way down to “Advanced”, turn OFF “Privacy Preserving Ad Measurment”.
Hope this helps someone else!
