"302 redirected" says everything - the request is redirected, exactly as I suspected.. I am not surprised that automatic download in RouterOS didn't work and I don't think it is caused by your device. More like something upstream.
this probably brings more questions than answers:
- why is it redirected?
- where does it go?
I can't answer why it is happening but if you find out where it goes, it might point you in right direction.
If you are curious what is happening, you can set a sniffer, record those packets, save it in file, download to computer and open it in wireshark:
/tool sniffer start port=80 ip-address=[:resolve upgrade.mikrotik.com] operator-between-entries=and
/tool fetch url="http://upgrade.mikrotik.com/routeros/6.42.12/routeros-x86-6.42.12.npk"
/tool sniffer stop
/tool sniffer save file-name=redirected.pcap
(enter those commands one by one, not together please)
If you don't have wireshark (and you don't want to install it), you can either view packets straight in RouterOS (but its complicated to find the right packet) or you can simply open the pcap file in notepad and look for line saying "Location: ...." there should be only one in the whole file.
