Hi,
I have installed this agent using the recommeded docker-compose.yml.

It seems to be installed properly:

But if I issue this command:
curl -v http://localhost:4061/iot/about

The result is:

How could I solve this.
Kind regards

After updating node and npm to the latest versions, and replacing the docker-compose.yml with this one (https://stackoverflow.com/questions/57944790/fiware-ttn-iot-agent) it is working properly.

I'm having the same issue and I guess @IoTopenTech wants to mean this one docker-compose.yml file

version: "3.1"

services:
    iot-agent:

Just to clarify. I'm going to try it.

Well, I would like to remark a few things.

• This docu seems apparently to be deprecated; I mean, I was in fact following that docu, but when you use the suggested docker-compose.yml file inside docker folder you are probably going to get that curl: (52) Empty response from server or as in my case curl: (56) Recv failure: Connection reset by peer

• To solve this, I've tried the docker-compose.yml which this answer in StackOverflow suggests.

• I've noticed a variation of this alternative docker-compose.yml is also suggested in the README.md inside the docker folder of the repo itself. However, is still nonfunctional due few typos/indentation issues. Also the docker-compose.yml included in the repo was not updated properly. Neither the mentioned docu.

• Once you've deployed the docker containers using that alternative docker-compose.yml, you have to be aware this new docker-compose.yml exposes a different port, 4041 instead 4061 (as the docu suggests). So your curl request has to take this into account: curl -v http://localhost:4041/iot/about then curl should be able to give you the right response: {"libVersion":"2.10.0-next","port":"4041","baseRoot":"/"}. You also can modify the container exposed ports in the docker-compose.yml and keep curl requesting to http://localhost:4061/iot/about; this is totally up to you.

In conclusion,

• The contributors have to update the documentation in order to get the web tutorial also upgraded

• Also I think both docker-compose.yml and README.md need to be upgraded.

Finally, this is my suggestion for a newer and fixed docker-compose.yml

I had the same issue. Any progress on updating the doc?
