My DSM 5.2 was doing weird stuff so I decided to do a clean install of DSM 6.0.2. I can't get QuickConnect to work (I need it because I can't port forward here). It worked in 5.2 with a serial and mac address from the excel file. I used the same sn and mac on DSM 6 and n can't even log in. Tried a new sn and mac, still nothing. Reinstalled 5.2 and used the old (from when it worked) sn and mac and still not working. Used again a new sn and mac and still not working. Can anybody help me with this?
