Error fetching code: 400

I am dependent on kite to trade as Pi doesnt work good for me and same is nest trader. I find the indicators in kite much more effective than Pi. however, for the last few days Kite is not working well for me. The customer care is also not able to solve the problem, Every time I try to load the charts it says that error fetching code: 400.

I would request zerodha management to let me know as to what has to be done. I am not able to trade because of this.
