I’ve been struggling with connecting to their servers no matter what I’ve tried on PC. I’ve tried disabling my firewall on my pc, disabling ipv6 on my network settings, resetting network settings, resetting my pc firewall settings, ipconfig commands, netsh interface. I called my isp (verizon) and they told me to disconnect my linksys router from the modem and connect to the game only using my modem with ethernet and this actually worked so they deduced it to my linksys EA7430 router being the issue. So I contact linksys tech support and they guide me through setting up port forwarding with my router and it works for the first time they are setup, I think everything is fine but it was only temporary. I wait a couple hours later with nothing changed and I cannot connect to the servers again. I’m completely lost on what to do
