Visual Studio 2019 16,4, Nop 4.20

Hi,

Since I switched to Visual Studio 2019 version 16.4, I get an error message.

I can start the shop and log in as an admin, but if I want to change to the admin area, the program crashes and stops with an error.

Class: HomeModelFactory => row 84
var rssData = _cacheManager.Get(NopModelCacheDefaults.OfficialNewsModelKey, () => _nopHttpClient.GetNewsRssAsync().Result);

error:
System.AggregateException: "One or more errors occurred. (Response status code does not indicate success: 503 (Service Temporarily Unavailable).)"

HttpRequestException: Response status code does not indicate success: 503 (Service Temporarily Unavailable).



Does anyone have the same problem and can help.

Best regards

Yes I have the same error
This is calling the nopCommerce news feed NewsRSS.aspx

Its not related to the VS version
Something with the nopCommerce website ?
Calling the url string in the browser works

https://www.nopcommerce.com/newsrss.aspx?version=4.20&localhost=true&hideadvertisements=false&storeurl=http://localhost:15536/

Problem is on this line of code

            var stream = await _httpClient.GetStreamAsync(url);

Thank you. I have disabled it now and it works.

The easiest 'fix' might be to comment out this line

\Presentation\Nop.Web\Areas\Admin\Views\Home\Index.cshtml
                        @await Component.InvokeAsync("NopCommerceNews")

It is the Cloudflare's DDoS protection blocking the request to NopCommerce. For more info, you can check this thread.
