BTC blockchain cannot get blockheight

[wahdatw]

Hi guys,

I am trying to add BTC blockchain to the opendax v2.6.66 it fails to get blockheight. Must the btc node be fully synced?

This is how I set it up on the admin panel. Can you please help?

Hi,
First check if the blockchain service is up and running.
docker ps | grep blockchain

If it is up and running check the logs
cd opendax && docker compose logs -f blockchian

If you couldn't find out what the problem is, you might send the blockchain logs here.

Thanks so much for the reply. The first command shows the docker is running.

root@vultr:/opendax# docker ps | grep blockchain
088a51b4b155 quay.io/openware/peatio:2.6.48 "bash -c 'bin/link_c…" 37 hours ago Up 37 hours 3000/tcp opendax_blockchain_1
root@vultr:/opendax#

But the second command returns in error:

root@vultr:/opendax# docker compose logs -f blockchian
no such service: blockchian

@behnammby when I run docker logs opendax_blockchain_1 I get this log. I see a reference to port 8545 but my bitcoin node is running on 8333 (default) and in the opendax admin pannel I did give http://ip:8333 as server. What do you recommend?

Sorry it was a typo! blockchain is correct I wrote blockchian!! :-)

The blockchain service is for all blockchains i.e bitcoin, ethereum etc. From the log we can see the ethereum blockchain has an error too. You can see what errors are for what blockchains from this part:
home/app/lib/peatio/ethereum/blockchain.rb

To concentrate on one blockchain only, you can temporary turn off all blockchains but the blockchain you wanna trace by going to tower->settings->blockchains and then review the logs by command:
docker compose logs -f --tail=10 blockchain

@behnammby thanks for your time. My log shows this. My node is has open RPC and have added it to opendax.
Would appreciate a fix.

Here is the log:

@wahdatw Apparently It seems you are having some trouble with your bitcoin node. A clienterror execution timeout means that your request took too long to complete and was terminated by the server. This could happen for various reasons, such as network issues, heavy load, slow queries, etc.
1- check whether or not the server is under pressure.
2- check if you can communicate with your node outside of the peatio. For example You can simply run a rpc call using curl or similar tools.

[behnammby]

@wahdatw I checked your running instance of node using the following command:
curl --data-binary '{"jsonrpc": "1.0", "id": "curltest", "method": "getblockchaininfo", "params": []}' -H 'content-type: text/plain;' http://173.230.131.103:8332/

An I got:
curl: (7) Failed to connect to 173.230.131.103 port 8332 after 112 ms: Connection refused

So certainly your bitcoin node has a problem. Maybe it isn't configured correctly. Have you opened the port 8332?

[wahdatw]

@behnammby Hey boss thanks for taking the time. I am still struggling with bitcoin node. Please check this. I setup my bitcoin.conf like this.

rpcuser=wadi4u
rpcpassword=wadi4u
server=1
rpcallowip=77.68.110.54
rpcallowip=127.0.0.1
rpcbind=0.0.0.0
whitelist=127.0.0.1
whitelist=77.68.110.54
rpcport=8332
datadir=/root/bitcoin-data

And I can curl from the server where I have setup my opendax.
root@ubuntu:/# curl --user wadi4u:wadi4u --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getblockcount", "params": []}' -H 'content-type: text/plain;' http://45.79.215.10:8332
{"result":182174,"error":null,"id":"curltest"}

So with curl I can get blockheight but my opendax is not able to get blockheight.
Is the problem with my bictoin.conf ?

@wahdatw could you check the blockchain log now and send me the error?
