What port does the Argon use to connect to the Particle Cloud?

Argons unable to connect to wi-fi network in setup flow.

Status: Reported

Customers experiencing this issue are able to go through an Argon setup flow up to the point of connecting to a wi-fi network. After inputting the password, the device will attempt to connect until such a point it times out, giving an error on the mobile application. (At this time, this is only tested and identified on Android.)

I was suffering from this issue number 4 until I fixed it by deactivating ipv6 on my router.
Wouldn't it be cool to mention this suggestion from @ScruffR under that thread as a potential workaround/fix?
thanks!
