Zwift Loop after upgrade

Bugs and Support
1

After the last update my Zwift that always worked, now it’s in a loop after clicking on Let’s Go. It initiates communication and returns to the Let’s Go screen again.
Zwfit Version: 1.1.5
Game Version: 1.32.2 (107473)

Please provide more details of your Zwift setup such as:

  • Device you’re running Zwift on and it’s specs (type, brand, specific model, CPU, GPU, RAM, SSD/HDD, WiFi/wired type, ANT+/BLE, Operating System and version)
  • Trainer/smart bike (brand and model)
  • All sensors in use (type, brand, model) and connectivity type (ANT+/BLE)

Also please ensure all devices are running current firmware (check using the manufacturer app), and the operating system on your Zwift device is up to date.

Hi CJ,

  • Device you’re running Zwift on and it’s specs (type, brand, specific model, CPU, GPU, RAM, SSD/HDD, WiFi/wired type, ANT+/BLE, Operating System and version)
    SO: Windows 10 with the latest patches
    CPU: Intel(R) Core™ i7-7600U CPU @ 2.80GHz 2.90 GHz
    RAM: 16,0 GB
    Disk: SSD
    WiFi: Intel(R) Dual Band Wireless-AC 8265 with driver update
    ANT+ Device: Garmin USB

  • Trainer/smart bike (brand and model)
    Dare2Ride Fuego 1.0 with latest firmwares

  • All sensors in use (type, brand, model) and connectivity type (ANT+/BLE)
    Everything always communicated via ANT+ protocol
    Power Source/Cadence: Favero Assioma Duo
    Heart: Garmin
    Controllable: Dare2Ride Smart Trainer

11:30am - I cleaned the temporary files of the browsers and the Zwift folder and the problem continued, but now at the end of the morning I tried to open Zwift again and it worked normally.

11:55am - I tried again and the problem came back when trying to communicate with the Zwift CDN.

Definitely some platform instability.

This happened to me once a week or so ago. Did a reboot of the PC and it was fine. It’s been perfect since.

Hi Stuart,

Never happened to me, only after the last update. I’ve restarted the computer and the problem continues.

7

You can use Zwiftalizer 2.0 and do a ping test to see if you can ping the servers.

Hi Gerrie,

I’m in Brazil and my latency is 220ms.
I emphasize that via Android I am not having any problem using the same internet connection. The problem is specifically in the Windows environment.

Hi,

After updating the NVIDIA manager responsible for my notebook’s GPU, the problem was solved.
