I have port 5683 opened which allows my Photons to connect, but I am having issues getting my Argon to connect to my WiFi.
Same port, but the Argon uses port 5683 UDP. The Photon/P1/Core use port 5683 TCP.
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 (since it would be capable of that) but the outbound connection isn’t.
My current workaround is to add a router that is either incapable of IPv6 or allows to fully deactivate IPv6 and use that routers DHCP.
Argon can't connect through app
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 suggestion.
Status.particle.io shows a system outage right now. I have 12 customers who went down all at once.
You saved my weekend!!! Thank you ScruffR
Continuing the discussion from Particle Mesh Known Issues and Fixes:
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?
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. Each Argon will rapidly flash cyan for ten seconds before blinking red once, then repeating. Is there anything else that I need to modify in my network? My Photons are able to connect successfully; do the mesh devices connect through a different IP that could be potentially blocked?
You can try adding
SerialLogHanldler traceLog(LOG_LEVEL_ALL); and see if you get any helpful output on USB Serial.
Thanks @ScruffR, I ran the suggested code and recorded the following error:

I can’t find any definitive solutions online to
Cloud handshake failed, code=17, and like I said above it is able to connect to a hotspot without problems so I don’t believe its an issue with device keys. Am I correct to assume that the above log shows the Argon trying to connect over port 5684, instead of the documented 5683?
I opened port 5684 over UDP and the Argon was able to connect.
