To execute it 'npm run build' the following error occurs:

To execute it 'npm run dev' the same error occurs:

Does anyone know if the problem is with the address PROVIDER: WEB3_WS_PROVIDER=wss://bsc-ws-node.nariox.org:443

Hi I am concerned if the project works on windows env. This is a free bsc websocket endpoint and this may not be worked. So you need to use another bsc websocket for subscribing bsc events.

Hi. Thanks for replying.

I tested it on linux, on "Ubuntu 20.04.2 LTS (GNU/Linux 5.4.0-73-generic x86_64)" on server aws, also tested on Virtualbox(ubuntu), but it worked normal on windows10 i configured windows10 to test and yes it is bad to configure and run on windows10, on ubuntu it was easy, until this connection message appeared. I created 3 free keys on https://bscscan.com/s_checkout but all are showing the same error. I hadn't thought of the free bsc websocket endpoint, that must be it. You have suggestions for a place to create free and paid endpoint, I searched for "free bsc websocket endpoint" but I didn't find anything like that. But searching I found https://docs.binance.org/smart-chain/developer/create-wallet.html and "https://docs.binance.org/api-reference/dex-api/ws-connection.html" I'm looking for other sources where I can find bsc websocket. If you or someone else has something in mind, I accept suggestions.

You need to get a new server. There are several rpc providers on the internet like ankr/getblock... You can deploy a full bsc node and receive websocket, http events. I hope this helps.

Thanks Thorhus.

I found the ankr.com address, I will create a token and test it. I'm going to research how to deploy a node in local host. Thank you for the clarification.
