Answer: Yes, it appears that you have used the same seed phrase in the past to open your wallet, but you are now having difficulty doing so. It is possible that the seed phrase you are using is incorrect, or that it has been changed somehow. It is also possible that your wallet has been corrupted or hacked, or that the software you are using is outdated or incompatible with your wallet. If none of these are the case, it is possible that your wallet is not properly synced with the blockchain, or that you are using the wrong network. If you are unsure of the cause, it may be best to contact your wallet provider for assistance.
