New Windows Installer causing redirect loops

Version Lucee
Servlet Container Apache Tomcat/9.0.35
Java 11.0.7 (AdoptOpenJDK) 64bit
OS Windows Server 2019 (10.0) 64bit
Architecture 64bit

Ran the installer on a completely clean windows server

When trying to access a page via IIS, it gets into an endless redirect

307 test.cfm?&_
307 test.cfm?&_&_
307 test.cfm?&_&_&_

Static files serve fine from the same folder.

Lucee pages running fine out of tomcat root.

Suspecting it must be an IIS thing.

Any ideas?

does tomcat have write access to it’s own directory?

The windows service account needed write permissions to the IIS directory.
