Unable to Access GWT CodeServer Outside of WSL Environment

I am encountering an issue with accessing the GWT CodeServer from outside the Windows Subsystem for Linux (WSL) environment. I'm hoping to get some guidance or assistance on resolving this issue.

The problem arises when attempting to access the GWT CodeServer running within the WSL environment from a browser outside of WSL.
Specifically, I can access the GWT application's main page from my browser by navigating to localhost:8001, but I cannot connect to the CodeServer at http://localhost:8501.

From within the WSL terminal i can telnet the port and it looks good, but i cannot from the outside host.

My theory is that the codeserver only accepts connections from localhost - but i do not know how to set a host="0.0.0.0" or something like that on the jetty running the codeserver.

We use the org.codehaus.mojo gwt-maven-plugin with these settings:
<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>gwt-maven-plugin</artifactId>
    <version>2.10.0</version>
    <configuration>
        <localWorkers>1</localWorkers>
        <skip>true</skip>
        <draftCompile>true</draftCompile>
        <noServer>true</noServer>
        <compileReport>false</compileReport>
        <logLevel>INFO</logLevel>
        <style>OBF</style>
        <sourceLevel>auto</sourceLevel>
        <extraJvmArgs>-Xmx7G --add-opens java.base/java.lang=ALL-UNNAMED</extraJvmArgs>
        <workDir/>
        <module>com.toh.manager.ManagerclientDev</module>
        <strict>true</strict>
        <port>8001</port>
        <debugPort>8010</debugPort>
        <codeServerPort>8501</codeServerPort>
        <runTarget>managerclient.html</runTarget>
        <hostedWebapp>${project.basedir}/src/main/webapp</hostedWebapp>
        <persistentunitcache>true</persistentunitcache>
        <persistentunitcachedir>/tmp/gwt-${project.build.finalName}</persistentunitcachedir>
    </configuration>
</plugin>

Please let me know if you need anymore information
