What's Wrong?

Since last Sunday Sonnet on CC has an error.
It says
"Server is temporarily limiting requests"
"API Error: Usage credits required for 1M context · turn on usage credits at claude.ai/settings/usage, or use --model to switch to standard context"
Than just above place to type I have information that Usage Limit reached.
It's not true.
I have full limits to use. Problem is only with sonnet, other models works fine.

What Should Happen?

Expected behaviour is session without errors.
