Generating deposit address error

[shinji12307084]

I have set the stack (2-4-stable) up with rake service:all with only changing the domain and subdomain in config/app.yml according to the instructions.

But it seems to me like up to this point, the setup is not complete.

I managed to login with the seeded users: Email: [email protected], password: 0lDHd9ufs9t@

Once I go to the wallet interface, the UI just shows me the message "Generating deposit address" forever. Sometimes "Failed to decode cookies" for version 2.3 of Baseapp.

I have tried configuring a blockchain node in the Tower according to the instructions in this article

https://medium.com/openware/how-to-configure-blockchain-node-in-the-tower-opendax-5e75e3264e18

but I am getting the same error as addressed by one of the responses of the article

curl: (6) Could not resolve host: parity

Then I check the blockchain logs of the Opendax deployment using the command

docker-compose logs -f blockchain

blockchain_1               | {"level":"WARN","time":"2020-07-03 11:09:27","message":"Error: Failed to open TCP connection to parity:8545 (getaddrinfo: Name or service not known). Sleeping for 10 seconds"}
blockchain_1               | {"level":"ERROR","time":"2020-07-03 11:09:42","message":"#<Peatio::Blockchain::ClientError: Failed to open TCP connection to parity:8545 (getaddrinfo: Name or service not known)>"}
blockchain_1               | {"level":"ERROR","time":"2020-07-03 11:09:42","message":"/home/app/lib/peatio/ethereum/blockchain.rb:60:in `rescue in latest_block_number'\n/home/app/lib/peatio/ethereum/blockchain.r

:in `block (3 levels) in run'"}

I have tried restarting the blockchain daemon with the command

docker-compose up -Vd blockchain

And recheck the logs, same error.

I also tried to bring up the optional cryptonodes component with the command

rake service:cryptonodes[start]

Restarted the blochain daemon, check the logs, same error.

Apparently the person from the Openware team demonstrating the set up has the same error

See around 19:40 of the Youtube video.

So I'm thinking that this must be a default behavior and I might not have done anything wrong, just the setup instruction is not complete.

If this is the case, probably a more comprehensive setup instructions would be useful.

If anyone could point out what I have done wrong, or guide me to completing the whole setup, I can help document it and make a pull request, for anyone in the future that might have the same issue setting up the stack.

rake service:cryptonodes[start] will start the parity node locally and begin syncing. If you don't have it setup somewhere and the exchange pointing to it, you won't get an address.

So Parity must be installed

[Galaxy-Traveler]

sudo snap install parity sudo snap install parity-ui

[Galaxy-Traveler]

Parity must be installed sudo snap install parity sudo snap install parity-ui cryptonodes.yaml volumes:

• ../data/parity:/home/parity/.local/share/io.parity.ethereum to ../data/parity:/home/app/snap/parity/16707/.local/share/io.parity.ethereum

[alinetskyi]

Parity must be installed sudo snap install parity sudo snap install parity-ui cryptonodes.yaml volumes:

• ../data/parity:/home/parity/.local/share/io.parity.ethereum to ../data/parity:/home/app/snap/parity/16707/.local/share/io.parity.ethereum

Apart from setting up parity, you also need to configure blockchain in the admin panel as well as the deposit wallet for that currency

Hi all, I'm having the exact same issue. I changed everything according to the above, but it didn't solve anything. Anyone has some more info?

[freakcoderz]

Nope, gave up on this.

Let's try it again: sudo snap install parity/////////////////////////// nano opendax/temples/compose services: parity: image: parity/parity:v2.7.2-stable restart: always command: | --chain=kovan --mode=active --interface=all --warp=true --snapshot-peers=10 --min-peers=5 --max-peers=10 --jsonrpc-interface=0.0.0.0 --jsonrpc-cors=all --jsonrpc-hosts=all --jsonrpc-apis=all --db-compaction=ssd --no-persistent-txqueue volumes: - ../data/parity:/home/parity/.local/share/io.parity.ethereum>>>>>>>>>>>>>>>>>>> ports: - "127.0.0.1:8545:8545" to services: parity: image: parity/parity:v2.7.2-stable restart: always command: | --chain=kovan --mode=active --interface=all --warp=true --snapshot-peers=10 --min-peers=5 --max-peers=10 --jsonrpc-interface=0.0.0.0 --jsonrpc-cors=all --jsonrpc-hosts=all --jsonrpc-apis=all --db-compaction=ssd --no-persistent-txqueue volumes: - ../data/parity:/home/app/snap/parity/16707/.local/share/io.parity.ethereum<<<<<<<<<on ubuntu<<<Location where parity was installed ports: - "127.0.0.1:8545:8545" SAVE cd opendax rake service:cryptonodes &&

For testnet is ok For mainnet you will need a ssd min 500GB-2TB

Blockchain mainnet min-450GB

[lucagrossi]

OK this works indeed..thanks for all your support! My general question for this is: why isn't this somewhere in a manual or is it so obvious for everyone (and only not to me ;))?

[Galaxy-Traveler]

There are questions that sometimes can't be answered????? The community will always help you. It's for testing and improvement

[lucagrossi]

Alright thanks again. It seems to working now, although I can't see that my deposits are processed. Furthermore I see that the CPU skyrockets and ultimately (after a minute or so) makes my system unstable after starting the cryptonodes. At Digital Ocean I'm not able to have more than 2 VCPU's and 4GB RAM at this moment for some reason. Do I need the cryptonodes to work before I can see my balance? or can I do this in a different way?

[Galaxy-Traveler]

What OS you use? Ubuntu: free -m sudo swapoff -a sudo fallocate -l 12G /swapfile sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile free -h

sudo sysctl vm.swappiness=10 sudo sysctl vm.vfs_cache_pressure=50 sudo nano /etc/sysctl.conf

vm.swappiness=10 vm.vfs_cache_pressure=50

save and reboot rake service:frontend

[lucagrossi]

That helped as well. Thanks! I tried to speed up the block fetching with this command: parity --mode active --tracing off --pruning fast --db-compaction ssd --cache-size 4096

However the chain started again at 0 (it is faster), but every time I restarts the cryptonodes now, it start back again at 0. Anyway to solve this?
