@shani33 did you try:

  • change server you are using (please click ico with the tools in left top corner and next choose servers and select another one)
  • synchronize your phone clock

?
Please also verify if your selected node has actual block height on https://nemnodes.org/nodes/

I’m not sure why this error comes out. Did you try all solutions proposed above?

If you want sell your tokens the more convinced and 100% sure way should be:
a) export your private key from mobile wallet (click account, click more button in bottom right corner, export account, show private key)
b) download nanowallet (https://github.com/NemProject/NanoWallet/releases/download/1.4.13/NanoWallet-1.4.13.zip) and unzip
c) run start.html, and import private key:

  • Sign Up
  • “Private key wallet” tab
  • Put private key from mobile wallet, wallet name, and provide password for secure .wlt file. Please also do backup your private key if you want use this account in future!
    d) your balance should show up in nanowallet and you can try send money from nano (Send tab)
    If you don’t know your address it will be available in “Send->Receive” in field “Pay to”

I tried all solutions.

Once i tried to exchange token before but i forgot to write message while exchanging I lost my tokens, I provide my nem address to expert later i received my coins.

Might be this reason I received this message.

I already installed nanowallet in my computer I’ll try these options too.

Thank you

Ok. Please check in nanowallet.

Hi pawelm

I followed all the steps and went okay…but the transaction with changelley didn’t go through, still pending “waiting for payment”.

I don’t know why it happen

#20

@shani33 could you give your public address and transaction hash you made?
Maybe you don’t put message code which is required by changelly or you sent money to wrong adrress ?

#21

you should open up a support ticket with Changelly. If you have confirmed you sent XEM to them, they will be the only ones that can help you finish the transaction.

I have contacted them waiting their reply

I have the same problem with Android wallet. After encrypting the message it went through, however, Changelly obviously cant recognise the encrypted message, so I still have Waiting for Payment and also because of that I now don´t have anything…

Also, I tried to make a new wallet. I transfered funds to the new one without any problems. Changelly address makes problems.

#25

With returning tokens only changelly can help you because xems are on they account now. They must process this transaction manually or do return because message is encrypted.

#26

Yes, I sent a ticket asking for refund. However the error was still in wallet with unencrypted message.

#27

I’m not sure why this error occurres. It’s only when you sending to changelly? What’s your public address?

#28

It is only changelly, but happens on multiple wallets.

Once I traded XEM to the Changelly but forgot to add message. They refunded it and sent it with 1 XEM transaction fee (dunno why that high, it was less than 1000 XEM). Later I tried to exchange XEM, so I tried to send them XEM again. This error occured. So I didn´t care, kept my XEM. But yesterday I wanted to trade on Changelly and got this error again. So I made a new wallet in the Android app, sent XEM to the new wallet, but the error was still there even while using the new wallet.

#29

I don’t have idea to tell the true why this error occurres. Did you check if it’s also happen on desktop wallet? Maybe try import and check ‘Sending failed! Previous importance transaction conflicts’

#30

No, I haven´t checked it yet. I think that it occurs only with changelly address and I am not going to send them more XEM until I get a refund. After refund is resolved, I can take a better look on this problem :confused:
