Error: Unable to connect to account

[oniabifo]

I installed the ilp-kit on Google compute Engine, The installation went smoothly, and after running
"sudo ./start.sh"

I get an error that says
"(node:32188) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Unable to connect to account"

I am able to navigate to my public url but I am not able to login, nor is it responding to any action.

Are there any trouble shooting steps can i follow to resolve this issue?

@oniabifo yes, check that the following three URLs all contain some JSON:

• https://yourdomain.com/ledger/
• https://yourdomain.com/api/config
• https://yourdomain.com/config.js

Then another thing you could try is to stop all containers and remove them (docker ps, docker stop, docker rm), remove the on-host postgres data (see `https://github.com/interledgerjs/ilp-kit-docker-compose/blob/master/docker-compose.yml#L31), and then run your docker-compose up command again (make sure you set all the environment variables, on my server I created a little 'up.sh' script which sets them each time).

Hello @michielbdejong , Thanks for the tip, but i want to make sure, i am on the same page with you, I see you have mentioned docker a couple of times, and i want to make sure i am supposed to be using docker even if i installed using the Google Compute Engine?

On the set up page, There were three options, Docker, compute engine, and heroku, i am using Google compute engine, so i just want to make sure i am on the same page with you.

Also, The three Urls shows an error that says "The requested page hasn't been found

I will follow your troubleshooting steps, and hope it helps. Thanks.

Ah sorry, I was confused, yes. The GCE instructions don't use Docker (the Azure ones do, that's what I was confused with). OK, then you should check the same URLs and make sure that all the processes started by https://github.com/interledgerjs/ilp-kit/blob/master/start-all.sh are working - maybe start them one by one in four separate processes. Also, make sure to copy https://github.com/interledgerjs/ilp-kit/blob/master/client/public/config.example.js to just config.js and edit it to use your domain name (the GCE instructions probably weren't updated yet to instruct to do that)

@michielbdejong i thought as much, well, i decided to start all over again with a fresh install to document the issues that i am facing.

I figured when i run the command "npm install" on the ilp kit, the only issue i had was with sqlite3 during the npm install. It returns an error saying

"node-pre-gyp ERR! Tried to download(403): https://mapbox-node-binary.s3.amazonaws.com/sqlite3/v3.1.9/node-v59-linux-x
64.tar.gz
node-pre-gyp ERR! Pre-built binaries not found for sqlite3@3.1.9 and node@9.3.0 (node-v59 ABI) (falling back to source compile with node-gyp)
npm ERR! code ELIFECYCLE

npm ERR! A complete log of this run can be found in:

Also thanks for the instructions, will be sure to follow it once i install sqlite3 successfully.

@michielbdejong I started the ledger, and then the api, and it returned an error on the ledger which says

"2017-12-17T22:02:22.495Z ledger:error-handler warn Unauthorized: Unknown or invalid account / password" on the ledger process and " UnhandledPromiseRejectionWarning: Error: Unable to connect to account" on the api process at the same time.

I have googled the error and i came across this link #97 Someone suggested creating a new DB and i am go to try that out. Although, i will like to ask, The account / password that is being used are the variables set in env.list?

LEDGER_ADMIN_USER={#}
LEDGER_ADMIN_PASS= {#}

Thanks

[michielbdejong]

The account / password that is being used are the variables set in env.list?

Yes, they are. Which operating system are you using on your Google Compute Engine server?

Reading about your experience makes me think it would be easier for you to use https://github.com/interledgerjs/ilp-kit-docker-compose on top of Google Compute Engine?

If so, maybe we should remove the GCE-specific install instructions from the ilp-kit readme.

[oniabifo]

@michielbdejong I am making use of ubuntu 17.04, I have used every version of ubuntu on there. I think i will use the docker on top of the GCE and see what happens.

Well the GCE install instructions i do prefer because i am a data engineer who is more familiar with backends options and do a little bit of programming every now and then, Most people with my background will prefer to use the GCE install instructions. I just think there isn't a lot of troubleshooting methods when problems are ran into, and i believe that has something to do with issues rarely being ran into.

I will still like to believe i am doing something wrong somewhere. I will like to ask, must all the processes be started before the ledger connects?

[michielbdejong]

The ledger can run by itself. The api process wants to connect to the ledger, and will complain if it can't. The webserver will try to proxy requests to the ledger, and you'll see a Bad Gateway error if it can't.

[oniabifo]

Funny enough, when i started the ledger the first time, i ran into an error "ledger:error-handler warn Unauthorized: Unknown or invalid account / password" before i even started the Api, now i do not get that error anymore, but still run into an once i start the api.

[michielbdejong]

that first one was probably about the ledger connecting to the database. have a look at an env var called something like LEDGER_DB_URI

[oniabifo]

@michielbdejong There is DB_URI which connects to the postgres DB in the env file.

[oniabifo]

why is the webserver.js using port 80? Does port 80 listens to the server? Can this port be changed? I figured there is a problem starting npm. "Error: listen EACCES 0.0.0.0:80 and Error: listen EACCES 0.0.0.0:443".

Of course this doesn't solve the issue of the ledger not connecting, but it seems once nginx is started, it starts listening on port 80 which makes the webserver not being able to start

[michielbdejong]

Right, that would require sudo privileges, yes. Try editing https://github.com/interledgerjs/ilp-kit/blob/master/webserver/webserver.js#L95-L96

[oniabifo]

@michielbdejong I supposed i asked that just to make sure it wont change anything in the folder, i am wondering maybe there might be some services that is supposed to listen to port 80 and port 443 before i go ahead and make the change.

But i am reading through each documentation in each folders, and i think the instructions on the Github page isn't the same. Some extra things need to be done for each folder(ledger, api, webserver, and client) before this app will be able to run to run successfully.

Once i am sure i have everything 100 percent going, would it be okay if i write a documentation for the steps?

[michielbdejong]

would it be okay if i write a documentation for the steps?

ah, that would be awesome! :)
