I have a synology server connected to my router. Everything is usually fine, except when i want to mount the drives through my Macs. Im on 10.11 but I noticed this before hand: I go to the 'shared' or network in Finder and my diskstation is there. I click on it, and it says almost immediately, 'connection failed.' I can try 'Connect as' but nothing new. I enabled the guest account, this didnt seem to help. But if I type the ip into the 'go to server' it works instantly, allows me to log in, and then mount the drives. However, after about 5 minutes if I try to go back, they all disappear and I need to remount them all. I have a user set up as the log in name of my 2 macs each, with the password identical to the log in password for the user on the mac. they have permission as admin just to be sure and r/w access to all folders. Anyone know why I cant log in from the finder but can through Connect to server?
