“405 method not allowed” for “DELETE” method - asp.net-core

Question

I'm getting a '405 Method Not Allowed' when I attempt for a DELETE in my staging environment.
Is there something I should be looking out for?
When I run it on my local machine (IIS 10.0) it works fine and is able to delete an ID but when I run it on my staging environment it doesn't work and returns a 405 error on swagger.
This only seems to be occurring for all delete endpoints
This is how I've implemented delete endpoints:
[HttpDelete]
[Route("{Id}")]
current output from response header:
allow: GET, HEAD, OPTIONS, TRACE
content-length: 1293
content-type: text/html
date: Mon, 14 Sep 2020 04:15:15 GMT
server: Microsoft-IIS/8.5
x-powered-by: ASP.NET
x-powered-by-plesk: PleskWin
I've got the current setup for my startup.cs
private static void ConfigureCors(IServiceCollection services)
{
services.AddCors(o => o.AddPolicy("testAppPolicy", builder =>
{
builder.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.Build();
}));
}
I know it's quite a vague question but any tips on where I could start looking on how to debug this situation?

According to your description and error message, I suggest you could firstly make sure you have installed the right asp.net core module for the staging server.
Then I suggest you could try to remove the WebDAVModule in the IIS server.
More details, you could try to modify the web.config as below format.
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<modules>
<remove name="WebDAVModule" />
</modules>
<handlers>
<remove name="WebDAV" />
<!-- I removed the following handlers too, but these
can probably be ignored for most installations -->
<remove name="ExtensionlessUrlHandler-Integrated-4.0" />
<remove name="OPTIONSVerbHandler" />
<remove name="TRACEVerbHandler" />
</handlers>
<aspNetCore processPath="yourasp.net core config"
stdoutLogEnabled="false"
stdoutLogFile=".\logs\stdout" />
</system.webServer>
</configuration>
