Can't access env - The certificate for this server is invalid - ERR_CERT_DATE_INVALID

No one (as far as I know) is able to access our test environment except my project manager.
Here’s what we have:


Note that I can access our dev env without issue.

  • Package Version:
    “forest-express”: “^7.9.4”,
    “forest-express-sequelize”: “^7.6.3”,
  • Express Version: “express”: “^4.17.1”,
  • Sequelize Version: “sequelize”: “~5.15.1”
  • Project Name: Sergic

Hello @JeremyV,

I have a few questions for you:

  1. Was it always like this, or did it change recently?
  2. Is it possible to open the developer tools of your browser, and spot the requests that are failing? It will help to find the origin of your issue.


1 it changed recently

Ok, it seems that the certificate used on your server is invalid. You can see the error net::ERR_CERT_DATE_INVALID. Chances are that this certificate expired today.

Can you check the details of this certificate?

In fact, your certificate expired on May 13th.

Thanks, I’ll check and keep you posted. Is it possible that only one user might be able to access anyway ?

Maybe he manually accepted the certificate on his browser

Indeed he did. Thanks a lot for your help.
