Issue withdrawing FLOW from Coinex

Hi I bought FLOW from Coinex and tried to send it to my ledger nano through port.onflow.org. It never arrived and then when I checked, I found this error message:

[Error Code: 1006] invalid proposal key: public key 0 on account d7ac95a418791a91 does not have a valid signature: [Error Code: 1009] invalid envelope key: public key 0 on account d7ac95a418791a91 does not have a valid signature: signature is not valid

Please let me know what happened or if there’s any way to fix this.
Also, I just made a Dapper Wallet and was wondering if I would have more luck sending the FLOW tokens there.

Thank you.

I would check with Coinex. It sounds like an error on their end.

Dapper Wallets can’t hold FLOW unfortunately, so if you want a non-custodial solution to hold FLOW, you’ll need to use ledger or Blocto.
