I have a mod_plsql application that works with ords from 2.0.2 to 3.0.2. However, with any higher version of ords upto 3.0.8, I get the following error

This error only appears in Safari on macOS and iOS webview; not Chrome, Firefox, or IE. The setup hasn't changed, except for replacing ords.war file in tomcat's webapps folder. The application is secured using Sibboleth V2
Apache/2.2.15 (Unix)
ProxyPreserveHost On
ProxyPass /pls ajp://localhost:8009/ords
Apache Tomcat/8.0.38
webapps/ords.war
ords 3.0.x
configdir: /swadm/etc
I download a new ords, unzip the files in /swadm/3.0.x
java -jar ords.war configdir /swadm/etc
cp ords.war ~tomcat/webapps
startup tomcat
