Can't send screenshots in private messages.

[Devil's servant]

When i trying send screenshot in private message i receive error "Failed to upload image data to cloud server"
I was looking for a solution to this problem, quite a few solutions to this problem were proposed, but none of them helped me. The most popular suggestions for solving the problem:
1) Switch to the beta version of the client (or switch to it and back to the standard one).
2) Turn off parental controls (or check the box next to the messages when you turn on the controls)
3) Run the client as administrator
4) Clearing the download cache
5) Re-login to account

Really weird that you can't send screenshots with parental control on
