I have port 5683 opened which allows my Photons to connect, but I am having issues getting my Argon to connect to my WiFi.

I opened port 5684 over UDP and the Argon was able to connect.

The Argon uses UDP port 5684. The Photon/P1/Core use TCP port 5683. (Answer edited, as the original answer was wrong.)

The port wouldn’t play a role in your Argon not being able to connect to your WiFi but only to connect to the cloud. If you have issues with your Argon not connecting to your WiFi you may run into the same issue I experience due to my DHCP server insisting in providing an IPv6 address to the Argon …

Thank you for the information @ScruffR , it seems that I did not explain my problem correctly. I am in fact connecting to my WiFi but am unable to establish a connection to the Particle cloud. My Argon is stuck rapidly blinking cyan. I am in the process of opening port 5683 UDP as per @rickkas7 sugge…

Status.particle.io shows a system outage right now. I have 12 customers who went down all at once.

The outage should now be resolved per status.particle.io

Thank you for the suggestion! @rickkas7 is helping to manage our Particle Mesh Known Issues and Fixes – we’re very close to releasing a standard fix that should resolve this issue, but if you identify other “workarounds” that ought to be included there, let myself or Rick know. Thanks for the help! …

My Argon’s are still having connectivity issues on my work network. They are currently running rc27 and are able to connect to a hotspot without issue. My work network has port 5683 open over UDP and TCP. I have tried disabling ipv6 routing, and I have tried limiting the number of DNS servers to two…

You can try adding SerialLogHanldler traceLog(LOG_LEVEL_ALL); and see if you get any helpful output on USB Serial.

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

Connectivity BLE // NFC

Yup, the Photon uses CoAP over TCP on 5683 but the Argon uses DTLS UDP which goes via 5684.
