No Zwift session in Companion app

Hi there,

When I open the ZC app during a ride, this activity is not recognized by the app.
The menu item “Game” is not displayed. This makes chatting through the app impossible.

What did I already try?

  • Update smartphone
  • Update ZC app
  • Update Zwift software
  • Update Windows
  • Reboot smartphone
  • Reboot laptop
  • Reboot router
  • Reinstal ZC-app
  • Firewall on laptop temporarily disabled
  • Firewall on network temporarily disabled
  • Airplane mode on smartphone ON
  • GPS on smartphone ON
  • Bluetooth on smartphone ON
  • ZC-app given access to GPS & devices nearby
  • PC and smartphone connected to the same WiFi network (2.4Ghz)

Can anyone help me? I would like to use the chat function during meet-ups that I organize.
I’m using Windows and Android.

Regards,

Ruben

try rebooting your wifi equipment

Unfortunately this didn’t help either.

Hi @Hipnie

Sounds like you’ve done most of the troubleshooting from this Support article.

This firewall is on your PC, or on your router? It sounds like you’re pretty tech savvy. If you’re comfortable logging into your router, you may want to open up ports on the firewall to explicitly allow this traffic.

Also - do you have a VPN app running on your PC, phone, or router? That will cause this symptom as well.

As long as you’re logged in to your router - you may want to refresh the table showing which devices are on your LAN. Check the IP and subnet masks for the PC and your smartphone are both on the same subnet. Being connected to the same WiFi network isn’t technically the same thing as being on the same subnet.

Summarized: It works! :partying_face:
Cause: Unclear


Thanks @shooj for your reaction.

Important note: The chat was working just fine a year ago.

Firewall
The firewall I mentioned earlier was on my laptop. Just now I also temporarily disabled the firewall on my network. This unfortunately did not fix the problem.

VPN
I am not using a VPN currently.

LAN-network
I checked what devices are on my LAN-network at the moment.
Even though I set the frequency of the WiFi to 2.4 GHz only, it indicates that my smartphone is using 5 GHz. After this, I again set my LAN network settings to 2.4 GHz only. In doing so, my smartphone still displayed “Band: Wi-Fi 5GHz”. Nevertheless, the 2.4 GHz connection suddenly does seem to have succeeded. My Zwift Companion app finally displays the “GAME” section again.
In my network settings, it says that my smartphone is still using the 5 GHz connection. Despite the fact that I have disabled it.

Special thing is: when I set my network settings back to 2.4 AND 5 GHz, my ZC-app still stays connected.

@Hipnie
Wooo! Thank you for letting us know it’s working again.

When Companion doesn’t switch over to game mode, it’s almost always a local network issue. Sometimes it’s fixed by rebooting the router. Other times, it’s more complicated. I’m glad that you’re tech savvy and were able to figure out the 2.4 Ghz band vs 5 Ghz distinction.

Yeah. Of course I wanted to share the great news :blush:
So I still don’t know what exactly caused it to work now.

Both laptop and smartphone work on the 5 GHz frequency.

Fortunately, it works well now.
Thank you for your help!

This problem, unfortunately, is back on.:frowning:
Has a solution been found in the meantime? @shooj
