Update to v8.16.3 broke the web interface in Scientific Linux 7.3

Summary

After updating the package to gitlab-ce.x86_64 8.16.3-ce.1.el7 using the RPM repo, the web interface is broken. It was working fine before the update.

I have the same problems that I had in #25159 (closed)

System: Scientific Linux 7.3

Web Server: Apache 2.4 - Using Apache forwarding

Using relative URL: https://<SERVER>/gitlab

Steps to reproduce

Update Gitlab to 8.16.3.

Expected behavior

Usable web interface.

Actual behavior

Web interface is broken.

Relevant logs and/or screenshots

I found nothing interesting in the web server logs.

Two screenshots:
