How did the largest European powers react to the successes of the Russian troops in the Russian-Turkish war of 1877-1877?

They reacted mostly negatively, this led to the fact that a few months after the ceasefire in San Stefano, the Berlin Congress followed, at which Russia and its allies in the Balkans were forced to make concessions, for example, the territory of Bulgaria was cut, Eastern Rumelia became autonomous until 1885, Serbia received less territory than it wanted. England and France were especially dissatisfied, they had their own interests in the Ottoman Empire, for example, the British annexed Cyprus shortly after the Berlin Congress.
