Hey all - we’ve been troubleshooting this issue for days now and it’s been hard to reproduce.
The fact that the workarounds are solving the issue for many, but not everyone hints at specific conditions on individual computers that are hard to reproduce for us at HQ.
I’ve started a fresh thread to continue troubleshooting. There’s a new thing (which version of IE / Safari is installed) that we’d like you to check and let us know (on that new thread). Thanks for your continued support of others in the community.
I had the same issue I managed to get it to work.
I had cleared all the cache, history and checked all the boxes on both internet explorer and Chrome, this didn’t work.
Uninstalled zwift reinstalled that didn’t work.
cleared everything history cache etc again still didn’t work.
Installed CC cleaner asked it to remove temporary internet files, cookies, recent documents, windows log files and windows error reporting.
This must have deleted something the others methods could not reach.
Now it all works.
I hope that helps you guys find the solution more efficiently
This issue kind of ruined my morning. At least I know I am not the only one.
Just paused my membership, not happy about paying for a service I cannot use.
Unfortunately nothing has worked for me. I’ve done everything that has been suggested but am still getting the 403 error…am using Windows and Microsoft Edge.
App developers used IE to make use of legacy Microsoft features such as ActiveX. In the case of Zwift, I assume the launcher uses basic browser capabilities to verify the current app version against the latest release, and fetch the updates as required. If they wrote the launcher a few years ago (i.e. pre-Win10), IE would have been the default browser to use for such simple functions. The fact that many apps do the same is the reason IE is still (silently) installed with Win10.
