Hi,

It would be great if you please check the firewall log and your system event viewer security log for
this issue. Please check either specific URL is blocked or not in log files.

Please share the exact URL which you are using in IMG tag. We are investigating this issue in more depth and will share our findings with you asap.

Please execute the following code snippet at your side in a standalone application and share your findings with us.

WebResponse response = request.GetResponse();
using (Stream responseStream = response.GetResponseStream())
using (FileStream fileStream = File.OpenWrite("C:\\Image.jpg"))
{
    byte[] buf = new byte[4096];
    while (true)
    {
        int bytesRead = responseStream.Read(buf, 0, buf.Length);
        if (bytesRead <= 0)
            break;
        else
            fileStream.Write(buf, 0, bytesRead);
    }

Hi,

Thanks for sharing the information. The error you facing is not related to Aspose.Words. It seems that you can not access image URL over network. Please check your network setting, firewall etc.

Hi,

Please accept my apologies for your inconvenience.

We have tested this scenario at different operating system and have not found this issue. May be we are missing some thing.

I checked this scenario over local network, one computer serve as server and other is client. The image is located at server. e.g http://serverIP/image.jpg (server IP is local network IP). Please confirm, am I using the same network which you are using?

Please share the exact URL which you are using in IMG tag.

We really appreciate your patience.

My Remote Server Image url Syntax looks as:
http://IPAddress:PortNumber/SelectImage.aspx?ImageID=8
or
http://WebsiteName:PortNumber/SelectImage.aspx?ImageID=8
