Error: Something took too long to do. [Discord]

I have this problem too. Apparently, it’s the bot not being able to connect to the websocket in-time, and this supposedly happens randomly on some hosting sites. The exact error is:

[2019-02-10 22:57:54]: ERROR Unhandled rejection: Error: Something took too long to do.
    at timeout.client.setTimeout (/app/node_modules/discord.js/src/client/ClientManager.js:40:57)
    at Timeout.setTimeout [as _onTimeout] (/app/node_modules/discord.js/src/client/Client.js:433:7)
    at ontimeout (timers.js:498:11)
    at tryOnTimeout (timers.js:323:5)
    at Timer.listOnTimeout (timers.js:290:5)

I don’t know how to fix it.
