I am testing against a 3rd party endpoint for timeouts when consuming their data, I've set my timeout to 5000 but my httpSertvice.post continues way past that time, am I doing something wrong?

My module setup;

imports: [
HttpModule,
HttpModule.registerAsync({
useFactory: () => ({
timeout: 5000,
maxRedirects: 5,
}),
}),

]

My httpService.post;

async sendHttp(xmlToSend): Promise<AxiosResponse\> {
xmlToSend = xmlToSend.replace(/>\s*/g, '>'); // Remove space after >
xmlToSend = xmlToSend.replace(/\s*</g, '<'); // Remove space before <
xmlToSend = xmlToSend.replace(new RegExp("\\n", "g"), '');
const headersRequest = {
'Accept': '*/*',
'Content-Type': 'text/xml'
};
return await this.httpService.post(
'https://blahblah/webservices/onlineflow.asp',
xmlToSend,
{
headers: headersRequest,
responseType: 'text'
},
).toPromise();
// return response;
}
