Monero Error Occurred Try Again Later
Subsequently the recent Monero upgrade several users reported that they were unable to access their Monero GUI wallet. Actually they were able to open their wallets merely tin't get the daemon to get-go. After starting; the wallet returns the following error message: "Daemon failed to commencement – Please check your wallet and daemon log for errors. Y'all can also endeavor to commencement monerod.exe manually".
Even nosotros got this error once, not with Monero wallet but with Electroneum GUI wallet. Nosotros left the wallet open to let daemon sync with the network. At some point the CPU crashed so we rebooted the system, opened the wallet again, logged in and when attempting to start the daemon it failed to connect to the network. It displayed an error message and the output returned by the wallet is "Delight cheque your wallet and daemon log for errors. You lot can as well try to start electroneumd.exe manually". So what causes this fault and how to fix this?
"Daemon failed to offset"
This is a common issue and is similar to "no block source found" error message in Bitcoin core and other QT wallets. There are 2 reasons why daemon fails to start. 1. Your antivirus might have deleted monerod.exe file or the firewall is stopping daemon from accessing the network. or ii. Your blockchain file might be corrupted due to ungraceful shutdown.
If your wallet is not online and if the blockchain is not in sync with the network then you'll not be able to employ your wallet. Merely practise not worry; your funds are safe and we can retrieve your wallet. Earlier you go on with this guide to be on safer side we recommend you to fill-in your wallet first. All you need to backup is your wallet mnemonic seed. Go to your wallet settings >> Show seed & keys, enter password and it will display your wallet keys. Backup this data and if you are looking for more detailed instructions and then please read this Monero wallet backup guide.
Alright! Now let'southward see how to fix Daemon connection failed mistake in Monero and other CryptoNote based cryptocurrency wallets.
Monero GUI wallet: Daemon doesn't start (Ready)
Nosotros know you might have done this several times. First close your GUI wallet. And then open chore managing director and end the post-obit tasks: monero-wallet-gui.exe and monerod.exe. Once the process is stopped, restart your wallet, enter your password and wait for a while. Sometimes information technology connects but we know this is not the solution that is going to piece of work for many. And then to fix daemon failed to start fault bulletin please follow the steps beneath.
This error message basically tells you that your GUI wallet is unable to run monerod.exe file. More information on why it failed to start can be found on the log file. If you oasis't modified the Monero blockchain location then past default the log file can exist found in the following location.
Windows: C:\ProgramData\bitmonero - bitmonero.log
Linux & Mac OS X: ~/.bitmonero/bitmonero.log
Now before you check the errors in log file allow's try to run the monerod.exe manually every bit suggested past your GUI wallet.
Finding monerod.exe file
Become to your Monero GUI wallet installation directory and you'll discover the following exe files: monero-wallet-gui.exe & monerod.exe. Practise not start monero-wallet-gui.exe file yet. Proceed to footstep number 2 if you find monerod.exe and if you practise non discover this file then probably your antivirus take quarantined it.
Open your antivirus software and add the whole wallet folder to the exclusion list. Once added, download the wallet file again and extract the GUI wallet files to the aforementioned folder location. It will put back the monerod.exe file. In one case monerod.exe file is restored let's run this file manually.
Run monerod.exe manually
At present open monerod.exe file and ensure that your firewall is not blocking any connections. It volition open command window and you will see a message stating synchronization started.
Information technology will display information on block height and how many days the sync status is behind. You lot can use the status command to cheque the sync status. At present leave this plan open and wait until the synchronization is consummate. Once the sync is complete; start monero-wallet-gui.exe file and at present your wallet should be able to connect. If this did not piece of work and then continue with the next stride.
Monerod.exe doesn't starting time
Is monerod.exe crashes immediately after start then try running monerod.exe with –log-level 4. This is done as follows: Create a .bat file in the directory where monerod.exe file is located and enter the following line. In one case done save it and then run the file. Yous can as well use –log-level 1.
monerod.exe --log-level 4
At present the daemon file should run and if the daemon is still not fetching any new blocks so it means your blockchain file is most likely corrupt. To ensure if it is actually decadent now let'south bank check the bitmonero.log file.
Navigate to the following directory.
In Windows C:\ProgramData\bitmonero. In Linux & Mac Bone information technology is ~/.bitmonero/. In one case you lot are in this directory open bitmonero.log file.
Note: These are by default hidden directories and you need to unhide to view and admission bitmonero.log file.
Open bitmonero.log file, scroll to the lesser and find if there is whatsoever error.
ane. No error in log file
If there is no mistake reported in the log file then first ensure that you have enough disk infinite to shop the blockchain file. If you do not have deejay space and then change the Monero blockchain data directory. Withal if this is not the example and if the log file does not bear witness whatever error message so ensure that both blockchain and wallet file path contains no spaces.
Some reported that if there is space left in wallet file path and so wallet won't piece of work properly. And then brand sure there are no spaces in the file path.
For example it should be similar: D:\Monero\MoneroGui\monero-gui-v0.13.0.iii
and not: D:\crypto wallet\monero\moneroGui\monero-gui-v0.thirteen.0.iii
Fix this and start the daemon. The wallet should work fine at present.
two. Error opening database:
If your bitmonero.log file contains the following error message then it ways the blockchain is corrupted.
Fault opening database: Failed to query m_blocks: MDB_BAD_TXN: Transaction must abort, has a child, or is invalid
This happens usually if the system crashes or if you shutdown the wallet ungracefully. Not to worry, permit'due south try to set this corrupted blockchain file.
Open the directory where monero-wallet-gui.exe and monerod.exe files are located. Now using the following command let'south try to save the corrupted file.
–db-salvage – This command try to salvage a blockchain database if information technology seems corrupted.
In windows create a new text document within the wallet binder and input the post-obit command in information technology. Once done save the text file as monerodfix.bat and run this file.
monerod.exe --db-salvage
On Mac Bone X and Linux type the following in the command terminal window.
./monerod --db-salvage
Note: If you lot are using custom blockchain information directory then yous take to utilise --data-dir flag.
Case:
monerod.exe --db-salvage --data-dir path-to-blockchain-directory
./monerod --db-salvage --data-dir path-to-blockchain-directory
Run monerod.exe file using --db-salvage and in most cases this should fix the corrupted blockchain. But even after this if you are nevertheless getting error opening database error then only way to prepare your wallet is past re-downloading the blockchain again.
Shut your wallet and in Windows go to C:\ProgramData\bitmonero and on Linux and Mac OS go to ~/.bitmonero/. Now delete p2pstate.bin file and lmdb folder (data.mdb & lock.mdb) and then restart your wallet.
The wallet volition now start re-syncing from scratch. Once it is fully synced yous are good to utilise your wallet.
We empathise that blockchain file size is enormous and downloading it over again from the start is going to take a lot of time and resources. But unfortunately this is the simply way to fix your wallet.
Blockchain file tin can become corrupt for several reason and in future if don't wish to get through all this then backup and have a copy of blockchain file locally. Also if you don't wish to download the blockchain over again then you tin save disk infinite and sync time by connecting your wallet to remote nodes.
Hope it helps. If you are still having problem using your Monero GUI wallet so delight let us know in the comments below.
