Typical network error when downloading updates

403 forbidden

web server is still launching and forming the table for file cache, try again later;



404 file not found

no update file on the server. Usually it happens when the update file is deleted from the server manually or by anti-virus program by mistake (folder C:\ProgramData\MyChat Server\updates\);



509 bandwidth limit exceeded

the server set a limit for simultaneous connections to control bandwidth. Try again later or disable limitation in MyChat Server settings;



11001 Host not found

your DNS is configured incorrectly (check the local file hosts), or there is an incorrect domain in the external address of your server;



10060 Connection timed out

the client can't connect to the server via the TCP and specified port. The reason might be a firewall on the server (add the server's WEB port to exclusions). The second reason is an anti-virus on the server that can block incoming HTTP requests. Add the file of the built-in WEB server NodeJS: "C:\Program Files (x86)\MyChat Server\node\node.exe" to exclusions;



10061 Connection refused

something is blocking connection between the server and client. Usually it is an anti-virus on the server, or on a client (although external traffic is blocked rarely)



10054 Connection reset by peer

connection interrupted on the server side. If the download process starts and then, after successful update download you receive this error, it means that connection quality is low (unstable WiFi connection). Or the network hardware (router) is configured incorrectly and blocks the transfer of large-sized packages;



10051 Network is unreachable

issues with network sub-system. Usually, the solution is a simple computer restart.
