Hey there,
I moved these reports to a new thread since it’s a different issue. Typically when I see the “Failed-Network” or similar errors when downloading from the website, it is related to either security or stability causing the download to not complete.
I normally recommend a power cycle of both the computer and networking devices. For the computer, shut it down safely and leave it unplugged for 20+ minutes. For the network devices just unplug them for 20+ minutes. Power on the network first and allow 10 minutes for it to set up before turning the computer back on.
I have also seen the error caused by security software such as little snitch (mac) or noscript (pc). Any similar security software can cause this error so disabling it temporarily to verify if it’s related may be a good idea.
Hope the info helps! Let us know if this works for you or if the problem persists.
