Unity version 2022.3.7f1, Windows 10,
Hello, we are having trouble getting Date and Time from internet. A warning messages came up “Non-Secure network connections disabled in Player Settings”.
Should we set it to “Always allowed” < Allow downloads over HTTP* < Player < under Project Settings, with a Warning message (Plain text HTTP connections are not secure and can make your application vulnerable to attacks.).
What is your thought on this? Do most online game Dev set this to “Always allowed”? What if we use www. instead of http? Interesting enough it does work by using <www.worldtimeapi.org/api/ip> Are there any downside?
Script for API see below.
