Regarding this one I’m not sure if those two are related. It is not specified why it is blocked (Сайт https://nextcloud.com не открывается)
But seems long time I host Telegram-proxy for my friends in Russia. Thanks God we have a huge time shift between lands, because during the day my outgoing channel has being fully used.
UPDATE:
I google 27-31-2018/Ид2971-18 and 2-1779/2018 it is cleared against Telegram.
