Hello everyone,

Chrome recently released an update to Chrome (version 63) that includes experimental support for TLS 1.3. Unfortunately, this is causing problems with our client-side web service that powers the JavaScript SDK. We are currently looking into this issue but in the meantime, there is a workaround available. The following steps need to be performed on affected versions of Chrome:

  1. In the Chrome URL bar, enter chrome://flags and hit Enter
  2. Once on the chrome://flags page, find the setting for TLS 1.3
  3. Change this setting to Disabled
  4. Relaunch Chrome

Once Chrome restarts, you should no longer receive the ERR_SSL_VERSION_INTERFERENCE error. We will update this post as we continue to research this issue.

  1. we are getting error on many websites, its comes for 1 or 2 second and then open website. I tested with should we do any thing on website?

  2. We have started getting an SSL error: “Failed to load Resource. An SSL error has occurred and a secure connection to the server can not be made.” After that we get a “Reference error: Cannot find label”

    I suspect the second error is happening because of the first, but I’m not sure. We haven’t changed anything, so not sure what’s happening.
