We're using the Google-Calendar API of your components and occasionally, customres get the message ("connection reset by peer", Windows API error 10054). I can't detet any pattern behind this, I'd exclude the antivirus software as reason, because the client only uses Windows Defender.
10054 error means the peer (in this case the server) has closed the connection. The reason is multiple: antivirus, firewall, network problems, server forces a connection close... Occasionally what means? hourly? one per day? weekly?
