Any transaction has to match an address perfectly so the chance of guessing one is damned near impossible. They represent a digital signature, that is why they are random and none of them are the same Roll Eyes

Neither a transaction nor an address does 'represent' a digital signature.
A transaction is being signed with the private key(s) which belong(s) to the public key(s) of the UTXO(s).
The signature is then being verified with the public key.

Neither of them are 'random'.
A transaction hash and an address do look random because they are an output of a hash function.

Another possibility is that you copied an address from the wallet of a different "coin" on your Nano S, like Bitcoin Cash.

Funny how noone came up with this idea yet Roll Eyes

@OP: Besides of BTC/bcash confusion, may it be possible you have confused 'Segwit' with 'Legacy' ?
With what number did your address (you have copied into coinbase withdraw field) start with (1.. or 3.. ) ?
And whats the first number of the actual address which received your withdrawn balance ?

If one of them both start with a 1.. and the other one with a 3.., it might be possible you simply just have opened your wallet once into 'segwit mode' and once into 'legacy mode'.
You can choose the address format in: 'Settings' -> 'Blockchain' -> 'Bitcoin' -> Either Segwit (Addresses starting with 3..) or Legacy (Addresses starting with 1..) .

Have you checked the "Bitcoin Cash" wallet on your Nano S to see if the address you copied is there? (Check the "sign message" tool, and start typing the address in the text box, see if it shows up)

This does indeed sound like you have been a victim to malware.

You should definetely find out who this exactly happened. Can you try to copy/paste ANY (valid) address. To see that you don't have a malware which does manipulate your copy/paste buffer.
Did you confirm the receiving address on your nano s device ? Can you also provide the firmware version of your nano s? Did you update it to 1.4.1 ?
There was a vulnerability in the secure element prior to this update. It seems to be highly unlikely that this is the reason for your loss, but anything is possible.

I did exactly that. except that the QR code is not recognized even though I'm using the QR code from the address with the watch only balance. so unless I can get the private code or I should say the correct code I'm doomed.

If your answer is yes, there's a high chance that your system is infected with clipboard malware, as suggested by bob123. In this case try copy / pasting a Bitcoin address into a txt file as suggested by him and check whether the Bitcoin address that gets pasted into the txt file is the same as the one you copied. If the pasted address is different from the one you copied: My condolences, your coins are lost, your computer is infected, reinstall your operating system and change all your passwords.

That's not good, I'm afraid you've become the victim of a malware attack. Always double check addresses between copy / pasting as there's malware out there that will change copied Bitcoin addresses on the fly before it gets pasted into another input field. While hardware wallets protect your private key, it can not prevent those kind of attacks which still require an additional level of vigilance on your side.

Did you try copy pasting Bitcoin addresses, as suggested by bob123, to confirm our suspicions? Copy / paste another BTC address from your ledger into the address field of your browser or the forum's message field. Check if it's the same address as displayed by your Nano S.

Did you buy the Nano S directly from ledgerwallet.com or did you use another reseller? (eg. Amazon, eBay)

I've just swept the bitcoin to blockchain.info using their app.

What did you do exactly?

I'm guessing your steps, and you just tell me whether I'm right:

1) You copied the address given by your Nano S into the Coinbase withdrawal field

2) You withdrew money from Coinbase to the copy / pasted address

3) You noticed that your Nano S doesn't recognize the address and doesn't receive the coins

4) You check the address that you withdraw to on Blockchain.info

5) You scan the QR code on Blockchain.info with the Blockchain.info app and it shows the balance in there

Yes / no?

when I go into the wallet within
the blockchain app it says watch only. does this mean its still processing and it will take a while
before they become available??

It's not processing. Watch-only means that you can only check the balance of this address but not send any money from it.

I've just swept the bitcoin to blockchain.info using their app. it shows in there in the balance.
now, when I want to send it to my wallet it does not recognize the QR code from my nano wallet
nor the QR code from the address where the bitcoin is. when I go into the wallet within
the blockchain app it says watch only. does this mean its still processing and it will take a while
before they become available??
to respond the previous member, I copied and pasted the address that was given to me by the
Nano s wallet. I also have a HW nano wallet which I used yesterday as well. I thought that I probably
used that wallet to do the transfer to no avail. this is very puzzling.

Please answer the following questions:

Did you check the address you have requested the withdraw to ? Does it match the address you have copied ?
Did you verify the address of the nano s on the in-built screen ? Was it correct ?

You might try to copy any bitcoin address (e.g. 1F9RJNfgWSYSBfAjvLEupsfWwJJLqRndan) and paste it into a .txt file. Is it correct?
If this address does not appear on your notepad when you try to paste it, you do have a clipping malware. In this case you didn't check the address before withdrawing and your coins are lost. A anti-malware scan should be run.

Coinbase should send you the coins to the address you have given them. So if you are sure you pasted the address correctly (and checked it), contact their support.

Good Morning: I need help please from you guys the experts. yesterday I sent a fraction of a bitcoin from my account on Coinbase to my hard wallet. so I copied the address given
to me by the Nano S and pasted it on coinbase to finalize the transaction. so far so good. now, the bitcoin went from coinbase to an address that is not on my Nano wallet. it went to another address
that I don't have a wallet for.I have no idea where that address came from. I have this address where it went and it shows there unspent. I need to manually send the bitcoin to my wallet. any suggestions please??
Thank you very much. Cry

when you say "manually" are you referring to IO without any other input device beyond your keyboard (command line) ?
