Hi @Cactus_Ducc,
There are some other things we can try which might help out with the issues you've been seeing. First, can you try setting up a Clean Boot on your PC to see if that makes any difference at all? If there's anything else running on the PC that could be related to these connection issues that may help to get around it.
For more details on how to set up a Clean Boot check out the EA Help website. Please let me know how it goes once you've had the chance to give it a shot.
