I'm trying to use the contract approve function, but I have this 401 error :

events.js:352 throw er; // Unhandled 'error' event ^ Error: Unexpected server response: 401 at ClientRequest. (H:\bot\pancake-swap\node_modules\ws\lib\websocket.js:604:7) Emitted 'error' event on WebSocket instance at: at abortHandshake (H:\bot\pancake-swap\node_modules\ws\lib\websocket.js:731:15) at ClientRequest. (H:\bot\pancake-swap\node_modules\ws\lib\websocket.js:604:7)

Does someone know what's wrong?

What's the code you are using? – Ismael Jul 29 '21 at 18:08
All I do is : const provider = new ethers.providers.WebSocketProvider('wss://apis.ankr.com/wss/XXX/YYY/binance/full/main'); – user78481 Jul 29 '21 at 18:56
@user78481 That isn't the whole code. I would ask ankr.com perhaps it is something in their end. – Ismael Aug 01 '21 at 01:18
Did you manage to find a solution? I am facing the same error. – Kristjan Retter Feb 11 '22 at 12:48
Hi Kristjan, I have no idea what the problem was, but I succeeded in changing from Ankr to Moralis if I remember correctly. – user78481 Feb 12 '22 at 23:21
