AngularJS $http.put returns 405 when published

Question

I have an ASP.NET project with AngularJS. I am using $http.put to update a certain record in the database and I need the .then to do something later. I have an IIS server. When I test the code locally using Visual Studio it works fine. However, once I move things to the IIS I am getting a 405 status.

the call I am using is this: $http.put(req, oB).then(function(r) { DoSomething(oB.Id); })

The object oB is defined in the function calling this request.

the function it is calling in the controller is:

[HttpPut("{id}")]
public async Task<ActionResult> PutOb(int id, Object ob)
{
    if (id != ob.Id)
    {
        return BadRequest();
    }
    var oldOb= _context.Object.Where(x => x.Id == ob.Id).FirstOrDefault();
    oldOb.Name = ob.Name;
    _context.Entry(oldOb).State = EntityState.Modified;


    try
    {
        await _context.SaveChangesAsync();
    }
    catch (DbUpdateConcurrencyException)
    {
        if (!obExisit(id))
        {
            return NotFound();
        }
        else
        {
            throw;
        }
    }

    return NoContent();
}

I even tried to just call the put without the .then but I was still getting the same error.

Update: Activating the FailedRequestTracing got me this in the logs.

After a many attempts I was able to solve the issue by following the post here. However, I had to not include the following part:

<handlers>
    <remove name="WebDAV" />
</handlers>

When this section was added I got a 500 error.
