UnableToCallCrlEndpoint error which end point need to be opened up

[AnCe01]

A web based UI flow works when I don't run it on the server. Now I'm trying to run the UI flow on a server. As part of the security rules the server is locked down and only opened for certain urls/endpoints. At the moment the firewall allows all the IP addresses mentioned in the limits and configuration documentation.

I now, however, receive the following error:

{
  "error": {
    "code": "UnableToCallCrlEndpoint",
    "message": "The request could be authenticated because the service couldn't reach the CRL endpoint. The firewall rules on the machine may be blocking the CRL, or it could be offline."
  }
}

With Error details:

"The request could be authenticated because the service couldn't reach the CRL endpoint. The firewall rules on the machine may be blocking the CRL, or it could be offline." 

Which specific endpoints need to be opened up to resolve this issue?

Have you checked this?

Yes I checked the firewall rules on the machine and if the server was offline.

I managed to get the flow working by making sure that all urls noted here and all urls noted here were white listed by my organization for the server I'm running the UI flow on. Thanks to that I no longer receive the error
