There are known issues with Safari on desktops (OS X, macOS) and on iOS devices that resolve URLs containing the string "localhost". Our recommendation is to try the following:
- Replace 'localhost' in the URL with the IP address of the machine. For example, if you are testing the URL "http://localhost:8080/index.html" try using "http://<machine_ip_address>:8080/index.html" instead.
- Make sure you are using one of the supported ports to test the URL. The list of all supported ports can be found here.
If the issue persists, contact our Support team.
