Could not connect to Twilio:

[ads692]

This is the message I get when I try to run the server:

Could not connect to Twilio:
undefined...

This is the message I see when I inspect the error on the webpage:

WebSocket connection to 'wss://eyj0exaioijkv1qilcjhbgcioijiuzi1niisimn0esi6inr3awxpby1mcge7dj0xin0.e…qwnsj9fx0.n96fejl1fmhbsp2oqvmzvvjx2a4rzesxcsj2rv1j1n8.endpoint.twilio.com/'
failed: Error in connection establishment: net::ERR_NAME_NOT_RESOLVED

I am fairly new to iOS programming and I followed all the steps to create the backend server. Somehow I don't know how to resolve it.
