Lost Connection when launching certain games

I did as you described above and was able to launch both games without any problems. I can't say for sure whether or not it's resolved since it doesn't always happen. I'll try launching both a few times throughout the day to check though. Hopefully it worked
and I thank you very much for your suggestion!

 

Have you tried the hard reset power down your console for 10 secs?

tried installing the games again
