    [telegram] <exru> I used default example for iroha
    [telegram] <exru>
    [telegram] <exru> Iroha stared with docker and port is open
    [telegram] <exru> npm i iroha-helpers - installed normaly too
    sorabot
    @sorabot
    [telegram] <exru> And connect to iroha with CLI working as needed
    [telegram] <Aleksandr> @iceseer we need your help here
    [telegram] <Sara> I've asked for some more specialised help (re @Aleksandr: @iceseer we need your help here)
    [telegram] <exru> Thanks a lot (re @Sara: I've asked for some more specialised help)
    [telegram] <Sara> We might get a reply in stone time, unfortunately, they cannot check this right now. Maybe someone else would be able to help before that though (re @exru: Thanks a lot)
    [telegram] <exru> Oh, ok! I'll be wating
    sorabot
    @sorabot
    [telegram] <Bogdan> Probably it's related to the remote repository accessibility or so. It also could be their side temporal issue. As a workaround to check that you may try using another connection or a VPN.
    UPD. Ah, yea, I see it's from /queries so you have installed the dependencies. In that case my suggestion is not applicable.
    [telegram] <Alexander> are you sure you try to establish connection from 127.0.0.1 ?
    you can try to change listenning address to 0.0.0.0:50051
    [telegram] <exru> I'll check for a minute (re @Alexander: are you sure you try to establish connection from 127.0.0.1 ?
    you can try to change listenning address to 0.0.0.0:50051)
    [telegram] <exru> I tried to use 0.0.0.0:50051 but the same result (re @Alexander: are you sure you try to establish connection from 127.0.0.1 ?
    you can try to change listenning address to 0.0.0.0:50051)
    [telegram] <exru> Port is correct (re @exru: )

    [telegram] <exru> According to error logs the problem lays in /lib/queries/index.js:36:20

    [telegram] <Sara> Hi! So, they checked the error - it is definitely a connection error, it's set up here in the code of the library (re @exru: According to error logs the problem lays in /lib/queries/index.js:36:20

    @sorabot
    [telegram] <exru> Ok. Where is a problem? In the library or my server configuration?
    How to fix it? (re @Sara: )
    [telegram] <exru> What about this? (re @exru: )
    sorabot
    @sorabot
    [telegram] <Alexander> 1. check port redirection if client and iroha on different VM or in container
    1. try to establish connection with telnet(or nc).
    2. You can try to run iroha-cli or make telnet connection from the same VM where iroha is running to be sure that connection can be established
    3. check firewall options if it is used
    4. check packets are transferring from library to iroha with wireshark or smth similar

    [telegram] <Stepan> Hi. What environment docker is used in? (re @exru: Due to Iroha docker the latest version)
    sorabot
    @sorabot
    [telegram] <Stepan> Hi all✋ If ERP support only HTTP/1.1, is it possible to translate an example in JS to VBS? required for gRPC HTTP/2.
    sorabot
    @sorabot
    [telegram] <♌︎ Leo> Maybe u should consider wrapping the iroha api as a web service and call from your client. Do note that the iroha JS library for browser doesn't support GRPC natively, you still need a GRPC proxy to bridge HTTP 1.1 to GRPC. (re @Stepan: Hi all✋ If ERP support only HTTP/1.1, is it possible to translate an example in JS to VBS? required for gRPC HTTP/2.)
    sorabot
    @sorabot
    [telegram] <Stepan> yes, this way was considered, but I would like to force ERP to run an external script for connect.
