HTTP Authentication failed when using Clover#initDeviceConnection from the JS SDK

I'm using the JS SDK to communicate with a clover device. When using the initDeviceConnection function to start a connection in order to send a payment to the Clover device sometimes I get the following error upfront:

 WebSocket connection to 'wss://apisandbox.dev.clover.com/support/remote_pay/cs?token=C030UQ53830477' failed: HTTP Authentication failed; no valid credentials available

And it tries it until it reaches the maximum allowed attempts:

It doesn't seems to have any consistent reason for receiving this error. After refreshing the page a couple times, with no code change it starts to work. Also the first time I received this I tried to restart the Clover device and afterwards it started to work again, thought I'm pretty sure it was due the time I took to do that.

Also it seems to relate to this question http://devask.clover.com/question/242... Sometimes this problems happens on the first instance of Clover I create, but I always get it after closing the first Clover instance I used, I instantiate a new one and try to initiate a connection to the device.

The development environment (apisandbox.dev.clover.com) is updated frequently, and this error typically indicates a software update is occurring on the server. This is how the browser is handling the failure of the server to provide SSL information, or there is an issue when upgrading the http(s) connection to ws(s).

Chrome will report this error if there is any issue during the upgrade process.

See https://tools.ietf.org/html/rfc6455#s...

So I shouldn't see this outside the sandbox, in production, right?

I don't actually see it too frequent when I first use the websocket, so the times I've seen it was probably due the reasons you mentioned.

But if I close the connection and then try to open a new one that is always returns those errors. What should I do to avoid that? As I mentioned, I think it might be related to this http://devask.clover.com/question/242...

Your second scenario (But if I close the connection and then try to open a new one...) is related to the issue you linked to.
