Hey @codeleaf00,
Can we try running through some other troubleshooting steps to see if we can help with the Code:Net errors you've been seeing? I saw that you already tried flushing the DNS, but there are some other things that may help.
When you have the chance I'd recommend checking out the basic connectivity troubleshooting steps from the EA Help website first to see how that goes. If you're still getting the same error after that check out the PC-specific steps as well.
Let me know how that goes once you've had the chance to give it a try. Thank you!
