Hey guys, currently have quite a few s4 miners up n running, all but one wont let me ssh. When entering username-root password-admin is says invalid password. Performed several resets and still nothing. I can login using webpage just fine enter the password change settings n so forth, but even when i go into System/Administrator to change current password it still claims its invalid. I've flashed the newest firmware to it few different times thinking it was a bad flash but still the same issue. Any ideas?

are you logged as admin? otherwise if this is a vps that you have purchased you could ask the provider for a hard reset of your password

its not a vps, its connected right to my home router, i can login 192.168.2.xxx using root/root for user/pass and change whatever i want. but if i try using putty login as root/admin or even root/root it says invalid password.

try with mremoteng and set ssh version 2 under protocol

besides this are you using the correct port with putty? or you need maybe to forward it through your router

This could be it, each router must have a local ip; putty should try to access an specified S4, that means that it would be, depending on your settings something like:

192.168.1.xx <- 1 antminer s4
192.168.1.xx+1 <- another antminer s4 and so on,

You have to use different ports for each s4 (update their internal configuration) and then, on your router 192.168.1.1 <- you should forward connections from the outside to each s4 using the port established for it. If you need further help, please, let me know your router so I can point you where to go.

definetly not a port issue, i have 4 s4 miners i can ssh into 3 of them just fine including 5 s3 miners

Try using different ip address & change the utp cable.
Don't forget to restart your miner & pc after changing miner password & ip.

having a similar problem did you by any chance figure out why you can' shh in. I use to be able to do it no problem. Are you by any chance using westhash firmware?

That's quite curious.  It definitely wouldn't be a port issue if your actually getting a password prompt and being told what your entering is invalid.  My guess would be that the password has been changed from default but that should have been fixed when you did your first factory reset if that where the case.  Quite puzzling.

If a factory reset does not do it I would try firmware.  Try a newer firmware and don't check keep settings.  It should go back on ssh when doing this. (Firmware updates can go wrong if loss of power, etc, etc).   But I think firmware is what to look at.

Heck you could clone one of the sd cards on the working ones, change ip after.  And that would for sure do it and would keep settings.
