@Ali_R_Faraji @Dreambluezzz . Weighing in here to help. Games are so big and files are Gigs large. I have a pretty robust system and sometimes its the internet connection outside my home, or a storm between me and the ping, or a currupt file in the trillions of 1's and 0's.
Have played for 18 months and had numerous issues, but eventually found support here to fix the issue.
Number 1 fix: Full shut down, - Computer, internet modem and router. Wait 2 mins. Start Modem, wait, start router, wait, start computer, wait for full boot and connection. Launch.
Number 2 fix: If 1 did not work, Reboot, Delete settings folder in SWBF2 folder in documents folder. (Holds your personal set of info locally). Reboot, Launch Origin. Launch game, and let it gather info from server to replace that folder. Launch!
Number 3. Whenever you play, make sure you reboot just before playing to get a clean boot and all the resources your computer has will be dedicated to the game. Runs faster and better. When finished, reboot before you load the game again as sometimes old data in your file will be currupted if left open for too long with no activity.
Sometimes the game may need to be reinstalled. When you do this, reboot before and after. ( Before launching the game.. ).
It can be your side or the server side but rarely is it both. Sometimes I found that a device on my network is streaming and I lose all the internet I need ot connect. Rebooting the router and modem resets this.
Hope some of this helps.
