Can't connect to the backend!

[dmzmsz]

im having an issue that i could not connect to backend i've already configured the config.json

[moneroexamples]

There is also config.js (https://github.com/moneroexamples/openmonero/blob/master/html/js/config.js) where you need to setup apiUrl if needed (also set testnet or mainet flags).

If still no change, do you get any errors when running the backend server?

[dmzmsz]

this is what i am encountering now .. or do i really need to fully sync the daemon?

[moneroexamples]

did you run backend in testnet? From the screenshot it seems you want to connect to testnet. In this case, the backebnd should also be run as testnet, using -t option. For example:

./openmonero -t
Blockchain path: /home/mwo/.bitmonero/testnet/lmdb
Start the service at http://127.0.0.1:1984
get_current_height: not connected to deamon
Getting mempool failed 
Check block height: 1072645 no of mempool txs: 0

You dont need to be fully sync, nor even there is a need for monero deamon to be running. Just need blockchain path. By default, openmonero will search in a default path.

[dmzmsz]

im trying to run it on my local

[dmzmsz]

var config = { apiUrl: "http://127.0.0.1:1984/", mainnetExplorerUrl: "https://xmrchain.com/", testnetExplorerUrl: "https://testnet.xmrchain.com/", testnet: true, coinUnitPlaces: 12, txMinConfirms: 10, // corresponds to CRYPTONOTE_DEFAULT_TX_SPENDABLE_AGE in Monero txCoinbaseMinConfirms: 60, // corresponds to CRYPTONOTE_MINED_MONEY_UNLOCK_WINDOW in Monero coinSymbol: 'XMR', openAliasPrefix: "xmr", coinName: 'Monero', coinUriPrefix: 'monero:', addressPrefix: 18, integratedAddressPrefix: 19, addressPrefixTestnet: 53, integratedAddressPrefixTestnet: 54, feePerKB: new JSBigInt('2000000000'),//20^10 - for testnet its not used, as fee is dynamic. dustThreshold: new JSBigInt('1000000000'),//10^10 used for choosing outputs/change - we decompose all the way down if the receiver wants now regardless of threshold txChargeRatio: 0.5, defaultMixin: 4, // minimum mixin for hardfork v5 txChargeAddress: '', idleTimeout: 30, idleWarningDuration: 20, maxBlockNumber: 500000000, avgBlockTime: 120, debugMode: false };

[dmzmsz]

i try also running it on testnet but this problem occurs

how could i solve this?

[stoffu]

The error log says "not connected to daemon". Are you running monerod in testnet mode?

[moneroexamples]

Backend terminates because it cant access the mysql. On your screenshot the error msg writes:

""Access denied for user root " ....

Seems either root password in https://github.com/moneroexamples/openmonero/blob/master/config/config.json is wrong, or your mysql connection must be done using different user and password.

[darrylmalumbaga]

Im having a new issue now that incorrect date time value

how could i fix it?

[moneroexamples]

This occurs when you create a new account or login to one?

[darrylmalumbaga]

yeah it occurs when im going to create a new account and to login an account

[darrylmalumbaga]

[darrylmalumbaga]

what do you think is the reason behind this issue?

[moneroexamples]

The issue has been experienced before:

https://github.com/moneroexamples/openmonero/issues/51

Its caused by incorrect timestamp being written to the mysql. Do you have your blockchain synchronized, a bit? I does not to be fully sync, only just that there are some blocks there?

[darrylmalumbaga]

The problem now is when i run ./monero --test it wont synchronize , it just stuck

[darrylmalumbaga]

does anything wrong with my config.js?

[moneroexamples]

The monero deamon should be ./monerod --testnet. If you have something parts of old/stack blockchain just remove entire blockchain from ~/.bitmonero/testnet

If you run the openmonero backend on your localhost. the api url should be e.g., apiUrl: "http://127.0.0.1:1984/".

[darrylmalumbaga]

Here is my config.js its still not synchronizing , i've already deleted the entire blockchain in my testnet

[darrylmalumbaga]

and if i will run it on main net there is a problem ... "Failed created search thread for this account" upon creating an account

[stoffu]

What does the log of openmonero show?

[darrylmalumbaga]

here is it

[stoffu]

It says it can't parse the testnet wallet address. Are you sure you launched OpenMonero in the testnet mode by ./openmonero -t?

[darrylmalumbaga]

if i run it in testnet it gives me this error

[stoffu]

Is your testnet daemon synchronized? What do you see if you type status in monerod?

[darrylmalumbaga]

No .. it wont synchronized :( I've already deleted the entire blockchain in my testnet folder but still it wont synchronized

[stoffu]

You need to let it sync at least a bit. Wait for a while and see if it starts downloading blocks from the network.

[darrylmalumbaga]

here is my config.json is this correct?

[stoffu]

You config looks fine. No, I'm talking about your testnet monerod. Do you see it downloading blocks? What do you see if you type status?

Also, it's much more useful to paste text of logs (in full) rather than screenshots.

[darrylmalumbaga]

ok im sorry , its not downloading any blocks here is the logs

[stoffu]

Well I mean, you can just copy and paste the text here... :)

Wait for a few minutes to see if it shows some more messages. Also, type status.

[darrylmalumbaga]

The daemon will start synchronizing with the network. This may take a long time to complete.

You can set the level of process detailization through "set_log <level|categories>" command, where is between 0 (no details) and 4 (very verbose), or custom category based levels (eg, *:WARNING)

Use the "help" command to see the list of available commands.

Not a big deal, but it'd be easier to read log messages in the plaintext format. You can do so by sandwiching the text between a pair of triple backticks: https://help.github.com/articles/basic-writing-and-formatting-syntax/#quoting-code

This means that you haven't downloaded any blocks from peers after 11 minutes. Something seems wrong. Can you try again after deleting the blockchain folder at ~/.bitmonero/testnet?

[darrylmalumbaga]

i've already deleted the entire content on the testnet folder 4 times but still having the same problem :(

[stoffu]

Then it's a problem for the monero code, not OpenMonero. Open an issue there and/or ask question on #monero IRC channel.

[darrylmalumbaga]

if its possible that you can do a teamviewer with me? so you can see if its monero code or i just did something wrong hahahahaha

[stoffu]

I'd prefer private messaging on IRC. I'm always idling there with this nickname.

[darrylmalumbaga]

Im getting error now that "Error getting address" upon creating an account im running it now on mainnet

[moneroexamples]

Getting "Error getting address" in open monero, or official monero wallet/daemon?
