Business Central on-prem showing nothing but a white page after logging in on webclient

(1) ShareShare

Posted on by K-ROSE

Hello,

I've got an interesting issue regarding a new installation of Business Central on-prem (CU7). After logging in using the webclient, the page goes white and doesn't load. The server is freshly installed, tried both Server 2016 and Server 2019. The installation is a basic demo environment. The only difference being the authentication method, which is set from Windows to NavUserPassword in both administration console and WebClient config and the certificate thumbprint.

Things I've tried:

  • Different operating systems, Windows Server 2016 and Windows Server 2019 (both from the Azure marketplace)
  • The WebClient works fine on the local machine itself (http://localhost:8080/BC130)
  • The WebClient does show the login screen from a remote machine (http://<dnsname>.westeurope.cloudapp.azure.com:8080/BC130)
    • After login in, the screen goes white. The following can be seen in the browser console:console.png
    • There's nothing in the server log, besides a successful authentication message
  • Tried disabling the firewall, without success
  • Tried different browsers, without success
  • Tried reinstalling BC, without success

Has anyone seen this behavior before?

    So, a few weeks later, we've discovered that using the external IP address instead of hostname (http://12.34.56.78:8080/BC130 instead of http://<dnsname>.westeurope.cloudapp.azure.com:8080/BC130) does in fact work. But no solution for hostname just yet.
