For about a month now, I keep landing on the Ошибка: не удалось открыть страницу page, whatever publisher (Springer, Elsevier, De Gruyter, etc.) I try.
I’ve tried [sci-hub.do](https://sci-hub.do) / [sci-hub.se](https://sci-hub.se) / [sci-hub.st](https://sci-hub.st) either on Tor and on the usual browsers but to no avail.
Does anyone have the same problem ? It seems as if sci-hub were ok but there were no proxy available, but this has been lasting for a long time now.
