"サムスンギャラクシーACE S5830を持っています Googleが正しく機能している間に、どの市場で「接続なし」エラーが表示されているのは、「私は何をすべきですか？
"I have a SAMSUNG GALAXY Ace S5830 in which market and you tube are showing a 'no connection' error while google is working properly " what should i do?
You say Android "Market", which is an old version of Google Play. The Ace is an older device, and I imagine that in your case it's just been reset to factory settings, so many old versions of applications remain. These need updating.
The Market app should be updated automatically. Once that's done, then you'll be able to update You Tube and any other.
I had a Galaxy Ace and had to update eventually.
