It definitely sounds like something is interfering with the connection.
Something you can try is switching regions and seeing if you can connect to say the Americas or Asia. If it lets you connect to any other region, then it is very likely a network or connection routing issue.
In those cases the following should help:
Try doing an extended power cycle on your system. Turn off all devices including the modem. Wait 30 minutes, turn on the modem, wait 5 minutes, turn on any network devices, wait 2 minutes, turn on your computer and try the game.
You can try switching your DNS settings to use a free public DNS servers instead of your ISPs Servers:
We do not have individual steps for specific modems or routers so if you need assistance accessing or updating the devices, contact the device maker/provider.
Sometimes firewall or routing software/hardware will have some advanced settings to prioritize and manage types of network traffic. Normally that is not an issue but we have seen situations where it can interfere with the delivery of the data for our games/voice chat.
Let’s try turning off these features:
RoG (ASUS Routers Only)
Security firewalls (Some ISP provided modems)
Not all devices will have these options and the steps for turning these functions off will be different depending on the make/model/software version of the devices and programs involved. If necessary look at the documentation for your security and routing products to find out how to turn these options off.
In some cases there is a corrupt or misconfigured setting within the router or modem. We cannot say what that might be offhand but the easiest way to resolve these conflicts would be to factory reset the router and/or modem.
You may need to look up your specific model for the steps on how to do this and in some rare cases you may need to have this done by the ISP. Feel free to reach out to them for assistance if necessary.
Some folks have reported that a VPN gets them around the issue. Please note we do not support VPN usage though we do not prohibit its use with most of our games. Some countries around the world, do restrict VPN usage so you will want to research these restrictions for your country before attempting to use a VPN.
Many VPNs offer a demo or trial version of their service to allow you test without commitment.
If a VPN solves the issue for you then the issue lies with your network, your ISP, or the path they send you through to get your data to us. You can work with your ISP in these situations to help them hunt down and address the routing issue.
