Alright! Now let's see how to fix Daemon connection failed error in Monero and other CryptoNote based cryptocurrency wallets.

Monero GUI wallet: Daemon doesn't start (Prepare)

We know you might have done this several times. First close your GUI wallet. And then open job director and cease the following tasks: monero-wallet-gui.exe and monerod.exe. Once the procedure is stopped, restart your wallet, enter your password and wait for a while. Sometimes it connects merely nosotros know this is not the solution that is going to work for many. So to fix daemon failed to kickoff mistake message please follow the steps below.

This mistake message basically tells you that your GUI wallet is unable to run monerod.exe file. More information on why it failed to commencement can exist found on the log file. If you oasis't modified the Monero blockchain location then by default the log file can exist institute in the following location.

Windows: C:\ProgramData\bitmonero - bitmonero.log

Linux & Mac Os X: ~/.bitmonero/bitmonero.log

Now before y'all cheque the errors in log file allow'southward endeavor to run the monerod.exe manually as suggested past your GUI wallet.

Finding monerod.exe file

Go to your Monero GUI wallet installation directory and you'll find the following exe files: monero-wallet-gui.exe & monerod.exe. Practice not start monero-wallet-gui.exe file nevertheless. Proceed to pace number 2 if y'all find monerod.exe and if y'all do not find this file so probably your antivirus have quarantined information technology.

Open your antivirus software and add the whole wallet folder to the exclusion list. Once  added, download the wallet file once again and extract the GUI wallet files to the same folder location. Information technology will put back the monerod.exe file. One time monerod.exe file is restored allow's run this file manually.

Run monerod.exe manually

At present open monerod.exe file and ensure that your firewall is non blocking any connections. It will open command window and you volition run into a message stating synchronization started.

Information technology volition display information on block height and how many days the sync status is behind. You tin employ the status command to cheque the sync status. Now leave this plan open up and look until the synchronization is complete. One time the sync is complete; outset monero-wallet-gui.exe file and now your wallet should be able to connect. If this did non work then proceed with the next step.

Monerod.exe doesn't first

Is monerod.exe crashes immediately after offset and then endeavour running monerod.exe with –log-level 4. This is washed as follows: Create a .bat file in the directory where monerod.exe file is located and enter the following line. One time done save it and and so run the file. You can too use –log-level one.

monerod.exe --log-level four

Now the daemon file should run and if the daemon is all the same not fetching whatever new blocks then it ways your blockchain file is near likely corrupt. To ensure if it is really corrupt now permit'south check the bitmonero.log file.

Navigate to the following directory.

In Windows C:\ProgramData\bitmonero. In Linux & Mac OS it is ~/.bitmonero/. Once you are in this directory open bitmonero.log file.

Note: These are past default hidden directories and yous need to unhide to view and access bitmonero.log file.

Open up bitmonero.log file, curlicue to the lesser and find if there is any error.

i. No fault in log file

If there is no error reported in the log file then offset ensure that you accept enough disk space to store the blockchain file. If yous practice not have deejay space then change the Monero blockchain data directory. However if this is not the case and if the log file does non show any mistake bulletin and then ensure that both blockchain and wallet file path contains no spaces.

Some reported that if there is space left in wallet file path then wallet won't work properly. So make sure there are no spaces in the file path.

For example it should be like: D:\Monero\MoneroGui\monero-gui-v0.13.0.3

and not: D:\crypto wallet\monero\moneroGui\monero-gui-v0.13.0.iii

Fix this and showtime the daemon. The wallet should work fine now.

2. Mistake opening database:

If your bitmonero.log file contains the post-obit mistake message then it means the blockchain is corrupted.

Fault opening database: Failed to query m_blocks: MDB_BAD_TXN: Transaction must arrest, has a kid, or is invalid

This happens normally if the system crashes or if you shutdown the wallet ungracefully. Not to worry, let's try to set up this corrupted blockchain file.

Open the directory where monero-wallet-gui.exe and monerod.exe files are located. At present using the following command allow's attempt to save the corrupted file.

–db-relieve – This command try to relieve a blockchain database if it seems corrupted.

In windows create a new text document within the wallet binder and input the following command in it. In one case washed save the text file every bit monerodfix.bat and run this file.

monerod.exe --db-relieve

On Mac Os X and Linux blazon the post-obit in the command concluding window.

./monerod --db-salvage

Note: If you are using custom blockchain data directory then you have to employ --information-dir flag.

Instance:

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 afterward this if you are yet getting error opening database fault and so merely way to fix your wallet is by re-downloading the blockchain again.

Close your wallet and in Windows go to C:\ProgramData\bitmonero and on Linux and Mac OS get to ~/.bitmonero/. Now delete p2pstate.bin file and lmdb folder (data.mdb & lock.mdb) and so restart your wallet.

The wallet will at present starting time re-syncing from scratch. Once it is fully synced yous are adept to use your wallet.

We understand that blockchain file size is enormous and downloading it once more from the start is going to have a lot of fourth dimension and resource. But unfortunately this is the merely style to set your wallet.

Blockchain file can become corrupt for several reason and in future if don't wish to become through all this then fill-in and have a copy of blockchain file locally. Also if you don't wish to download the blockchain again then you lot tin save disk space and sync fourth dimension by connecting your wallet to remote nodes.
