I can't log into my EA account without a VPN. I live in Zaporizhzhia.

Good afternoon, my name is Nikolai, I'm from Zaporizhzhia, Ukraine. This morning I accessed the EA app without any problems, but this evening it showed an error about service limitations. I gave my friend my account details, and he's from Lviv, and he accessed it without any problems. I decided to try a VPN and was able to launch the app. Could you tell me why this happened? I can't access the app without a VPN anymore.
