Login page is not working ERR_TOO_MANY_REDIRECTS

Issue/Introduction

Having installed DX platform with SSL certificate files the UI pages are not working. I can verify the certificate is correct via browser. When I proceed to continue, "This page is not working" error appears. (ERR_TOO_MANY_REDIRECTS). This happens for any url attempted e.g. apmservices-gateway.dx.tmp.mydomain.com,  apis.dx.tmp.mydomain.com, es.dx.tmp.mydomain.com etc

Cause

The SSL certificate had been generated using wildcard notation using an address *.tmp.mydomain.com. Wildcard notation can only be used for one level so in this instance would need to be created for *.dx.tmp.mydomain.com

Environment

Release : 20.2

Component : CA DOI Foundations

Resolution

In this instance the customer changed the DNS entries to fit the generated certificate but could instead have generated a new certificate with the modified wildcard setting
