Error #0328: impossible to download the file "name", network error XX: "desc"
 

Error description

A network error occurred while attempting to download a file uploaded on MyChat Server via http/https. As a rule, such errors deal with incorrectly configured routers or firewalls on the server. Sometimes traffic is blocked by antiviruses.

 
Problem solution

Provide an option to download a file via a specified address and port via TCP protocol. For example:
 

[21:42:54] [ERROR] Error #0328: impossible to download the file "https://myhost.com/files/fb72c5e56cb0deaaa17b8deef2275328f011a8e4.pdf", network error 11001: "Host not found"

 

That means if there is no access to the address myhost.com via TCP 443 (https). This error indicates about an incorrect domain name or DNS is unavailable.

 

Another example:

 

[21:45:32] [ERROR] Error #0328: impossible to download the file "http://213.130.24.149:8080/files/fb72c5e56cb0deaaa17b8deef2275328f011a8e5.doc", network error 10060: "Connection timed out"

 
No access to the address 213.130.24.149, port 8080 TCP. The server does not respond. Incorrectly specified external "white" address of your server, or access is closed by a router/firewall/antivirus or incorrectly configured network software.
