"Missing Permissions" on change_nickname (HAS PERMISSION)

This is the code I’m using to attempt to change the nickname of a user: await client.change_nickname(message.author, newnick)

The role is at the top of the role hierarchy and has the necessary permissions to change nicknames: The role is assigned to the bot:

And yet discord.py still throws a permission error:

Ignoring exception in on_message
Traceback (most recent call last):
  File "/home/pi/.local/lib/python3.5/site-packages/discord/client.py", line 307, in _run_event
    yield from getattr(self, event)(*args, **kwargs)
  File "rankgiver.py", line 28, in on_message
    await client.change_nickname(message.author, newnick)

    raise Forbidden(r, data)
discord.errors.Forbidden: FORBIDDEN (status code: 403): Missing Permissions

Sending messages works just fine. I’m stumped.

the OP didn’t said anything at the end

My bad, totally forgot about this. Fairly certain enabling 2FA fixed it in the end. Thanks @Harmon758!

the bot needs to have a higher role than the person you change the nickname for.
