[Solved] Unable to Launch GTA5: Experiencing #3000.108 Error with Social Club and Rockstar Games Launcher

Hi, I have a problem most likely with the internet, it all started yesterday when I wanted to launch GTA5. I got message #3000.108 that I could not connect and I am offline. I have tried a million ways, I have done everything RockstarGames says to fix the problem (link below). I checked the link speed, I changed DNS servers, I restarted the router several times, I reset winsock and IP address, tried windows powershell sfc / scannow. I can't launch Launcher or go to social.club. I am practically convinced that it is the fault of the router or the internet (?) Because I can easily access the website after connecting via a different internet, e.g. LTE from a phone, laptop and other devices. The problem occurs wherever I connect to the home internet. I even did a complete format of the computer to get rid of win11 because I thought the problem might be in it, but the computer reinstalled it and I can't change to win10 anymore (unfortunately).

Error code #3000.108 is banning the IP address to the router. I wrote to R* and they fixed my problem with no problem. It seems to me that the appropriate "Subnet Mask" installed on the computer would work itself, but I do not know what they are and where to find them, I close the topic
