It may not be a port issue, although are you using upnp on the router ? manual port forwarding is rarely used or needed these days
The last time i saw behavior like this with the launcher was with bitdefender it was locking the processes so the launcher only worked once until the next reboot and rinse and repeat.
See this link for example of what occurred and the end result is exactly what you see now.
when i check router settings i see no options to turn upnp on or off but when i check the manual it says its supported. anyway i checked the link and it was no go i didnt have stuff at the link listed as my problem.
i had to manually forward my ports cause for some reason my game wouldnt launch. when i did that it was able to launch the launchpad GUI 1 time. then if i close it and try again, it does not open. i need help with this badly. when i said it was fixed in the other thread. this was the problem, it only worked 1 time then it stopped working.
Have you considered turning the firewall off on the router as a test to confirm this is the issue ?
it wont allow me to turn the firewall completely off its at the low setting LAN-to-WAN Allow all WAN-to-LAN allow all. but besides that I had a spectrum technician on the phone they forwarded the ports required for this game. it worked 1 time after restarting the router. but after that closing the launcher or the game 1 time and it doesn't work again, even if the port forwarded rules are still there in the router control panel. but still the game doesn't work.
do u know how to get the game to work all the time around the port forwarding issue?
