when trying to join https://t.me/hiveoschat_en for the first time Telegram tells me “this chat does not exist”
If you not see chat than probably you was banned due posting advertisements, offensive and obscene language, manifestations of racism or disrespectful attitude towards other chat users.
except that I’ve never tried to connect before so don’t think that is the case
Try first https://t.me/hiveofftopic_en it’s Hive off-topic channel
ask admin why you can’t connect to https://t.me/hiveoschat_en
thanks i try that
