We are getting reports that users are getting errors regarding our certificate on both app.adversus.io and api.adversus.io. The issue is related to the R3 Intermediate Certificate Expiration on the September 30th 2021. We strongly recommend reading this article if you have issues regarding certificates: https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/

If on Windows we recommend running Windows Update to update your device.

The issue doesn't seem to happen in Firefox as it is packed with its own certificate store.
