My game wouldn't connect to the front server for a few weeks after the current update. It eventually fixed itself, but it's still a mystery as to why that was happening.
I know you've given up on the situation, but there must be a way to fix this issue. I did find this on another thread by the user, Flurr:
"I found this on another website with people on other game having the same problem, but wanted to help out so here what it said! Hope it helps!
Reset your network devices to make sure your router hasn't become flooded with data.
Release and renew your IP and flush your DNS to resolve any network conflicts.
Update your drivers to resolve any compatibility issues.
If you're using a wireless connection, optimize your internet connection to rule out a connection issue.
Try closing background applications to resolve any software conflicts.
ADVANCED TROUBLESHOOTING
-------------------------------------------
Old network card drivers and settings may affect your connection in the games. Try troubleshooting your network card.
Check your network configuration to find any issues with your firewall, router, or port settings.
If you're using a VPN, try removing it.
Disable any proxies that may interfere with the login module.
Run a security scan to remove any viruses or malware infections.
Disable or temporarily uninstall any security programs, which may mistakenly identify the login module as a security threat.
Old firmware on your modem and router can cause issues with complex game connections.
Now this is from a DIFFERENT game so not sure if it will work...The website thread was pretty old, but I hope it helps you out and doesn't cause any serious problems."
I hope this issue gets fixed so that you can enjoy the game again.
