Problem with loging into account with web browser "Login error"

[baziorek]

All steps I've done in clean newest Kubuntu 19.10 with all updates (Kubuntu installed only to run wallet, no more programs installed):

$ sudo apt install git npm docker-compose -y
$ git clone --depth=1 https://github.com/soramitsu/iroha-wallet-js.git
$ cd iroha-wallet-js/
$ git rev-parse --short HEAD # current version hash is: 8ee46b0

Then I tried to run docker:
sudo docker-compose -f docker/docker-compose.yaml up
but I've received error:
ERROR: Service 'grpcwebproxy' failed to build: The command '/bin/sh -c dep ensure' returned a non-zero code: 2
which I've solved with:
sudo apt-get install libgrpc6 golang-grpc-gateway golang-github-grpc-ecosystem-go-grpc-prometheus-dev -y, because after that the docker's command run succesfully.
While previous command was running in one console tab, I've done in next tab:

$ npm install
(...)
added 1577 packages from 1188 contributors in 92.432s
$ node scripts/setup.js

After that I installed yarn as described here:
https://stackoverflow.com/a/47680012
then I prepared environment and run service with success:

$ yarn install
(...)
Done in 127.26s.
$ yarn serve

After that I've seen URL address: localhost:8080, so I've entered the URL filling all fields with:
username: admin@iroha
key: 0f0ce16d2afbb8eca23c7d8c2724f0c257a800ee2bbd54688cec6b898e3f7e33
(taken from iroha-wallet-js$ cat scripts/[email protected]
Node IP: localhost
After pressing the LOGIN button message "Login error" was displayed.

So how can I log in?

It is similar closed issue, but without answer: #29

Hi! Try to set http://localhost:8081 value to node ip field

[baziorek]

It is working, thanks!
BTW: I suggest to update README.md with information about this.

I've also tried to use the wallet with docker images created according to iroha's documentation, so I've typed:

$ docker network create iroha-network
$ docker run --name some-postgres -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=mysecretpassword -p 5432:5432 --network=iroha-network -d postgres:9.5 -c 'max_prepared_transactions=100'
$ docker volume create blockstore
$ git clone -b master https://github.com/hyperledger/iroha --depth=1
$ docker run --name iroha -d -p 50051:50051 -v $(pwd)/iroha/example:/opt/iroha_data -v blockstore:/tmp/block_store --network=iroha-network -e KEY='node0' hyperledger/iroha:latest
$ docker exec -it iroha /bin/bash # this is just to check if OK

Then I've run the wallet:
$ yarn serve
After that I've tried to login:
username: admin@iroha
key: f101537e319568c765b2cc89698325604991dca57b9716b58016b253506cab70
(taken from official iroha's example: $ cat iroha/example/[email protected] f101537e319568c765b2cc89698325604991dca57b9716b58016b253506cab70)
Node IP: I've tried:

• localhost:50051
• localhost:8081
• ${IP addres of docker image}
• addresses above with http:// and https:// prefixes

Finally I've used grpcwebproxy manually:
./grpcwebproxy-v0.12.0-linux-x86_64 --backend_addr=localhost:50051 --run_tls_server=false --allow_all_origins=true --server_http_debug_port=8081
then it worked with IP address: http://localhost:8081, but it is not mentioned in README.md, so I'm not sure if it is official way to log in?
So my question is - is it possible to login into iroha's images created according to official iroha's documentation without grpcwebproxy? If so, what address shout be used?
