From Bloomberg's article:
https://archive.ph/Lx3gi"Gazprom said it isn’t able to fulfill its long-term contracts to supply gas due to unforeseen circumstances, said the people, who asked not to be identified because the information is private. Gazprom had no immediate comment."
"Gazprom has been delivering less gas than ordered by customers over the past month. The company cited problems with turbines that compress the gas that goes into the Nord Stream pipeline connecting Russia to Germany, while Ukraine has shut one of the entry point on the border with Russia to ensure safety after forces invaded a key compressor station."
