"Connection failure" error message at mid-ride

Bugs and Support
1

It seems to persistently happen around 20 minutes into a ride, I get the message connection failure, I go to the pairing menu and everything connects, I go back to the ride and I get the message connection failure, I go to the pairing menu and everything connects, I go back to the ride and I get the message connection failure, I go to the pairing menu and everything connects, I go back to the ride…
Eventually after 3-8 attempts it’ll stay connected, or I get sick of it, unpair everything and then pair again.

I switch bluetooth, wifi and mobile data off on my phone to minimise interference. Garmin Kickr core doesn’t have this problem with Rouvey or the Garmin app itself, and the fact that everything connects and shows power, speed cadence etc in the pairing menu leads me to think this is an issue with Zwift and nothing else.

The same problem, especially when I was climbing hard and found that the connection failed…

Are you losing data transfer at this time. Ie. No watts, cadence etc? Does your HR also go?

I switch my pair from WIFI to BLE and it backs to normal.

Thanks Martha, my issue is fixed!

I’ve gone through that document thoroughly and it makes no difference, I could be 10 minutes in or 40 minutes into a ride but the connection to my trainer will drop. The last few times it has only happened once during the ride but it’ll be out for for long enough that in a group ride, everyone would have ridden off into the distance.

Hi @stu_tv, Could you please specify what type of device you’re using? If you’ve received a " connection failure" error, first, you should try using a web browser or program that’s on the same network as Zwift to access the internet. If this doesn’t work, this article still has a few more things to try depending on your specific situation, so proceed accordingly.

Additionally, check on your device if there is any update available. If you need help on how to do it please, review this article.

If the problem persists please, contact our Community Support team—we’re here to help you out!

According to this primer on error messages, Connection Failure relates to communication failure with a paired device, not Internet access. Losing connection to the Zwift servers should be Connection Disconnected. (And these error messages should be clarified so that the failure mode is plainly communicated to the user.)
