ACLK_MAIN ERROR - "Connection Problem" With Proxy

I am having a problem connecting to the cloud with my netdata service, I am getting the message “Connection problem”
image

I have the netdata service set up with docker compose, the server has a proxy for output to the internet so it is configured to output through the proxy and also configured the no_proxy for localhost

I comment with **** the confidential data
I clarify that on the host server: I have the exports declared

I don’t know what the problem is due to, I know it is due to the proxy but I don’t know how to solve the problem, the proxy has the connection with the url [app.netdata.cloud] enabled, is another url that netdata uses missing? Is there any extra configuration that must be done in these cases when using proxy? thank you

Hi @Jonathan_Stampella

Is it possible to grep your error.log for any ACLK lines? Should show some more info on the connection status.

Thanks!

Hi, in error.log show this

Thanks Jonathan.

Have you followed the steps for defining the proxy here → Connect Agent to Cloud | Learn Netdata ?

I set the proxy but I don’t know what else I have to do, I’m lost with the netdata and proxy configuration! run the netdata-kickstart.sh script, first download it to my PC and then paste it on the server because I don’t have the url enabled for https://comunity.netdata.cloud and it gives me this:


Could it be because I don’t have that url enabled in the proxy?
Thanks

I solved the problem to connect to the cloud, it was the docker image that had an old version of netdata. Now when I go to my profile in netdata I can’t see the connected node


Is there a waiting time until the node is seen online? or do you have to enable something on the server?
or maybe the same error continues and only the interface was updated.

I noticed that in the info it shows me node_id as null

Is there something I’m missing?

inside the netdata container it has a connection with app.netdata

It appears that the connection still doesn’t work…

Can you post the output of http://localhost:19999/api/v1/aclk? Can you check again the error.log for ACLK entries?

I can’t figure out what is failing, what DNS application are they pointing to? apart from app.netdata.cloud does it point to another?

Any information about the proxy server and it’s configuration? What is the actual proxy server SQUID, ntlm?

Maybe I can add log there
2023-10-31 14:49:02: netdata ERROR : ACLK_MAIN : Expected response to start with "HTTP/1.1 " (errno 11, Resource temporarily unavailable)
to actually print what we received instead which could give us some hints.

Currently I can just see the proxy doesnt reply with HTTP/1.1 as expected but can’t tell why.

The type of proxy we use is “IP-based authentication proxy”

with telnet not working

I have enabled what is port 80 and 443 of the url app.netdata.cloud, is it only that url to which the netdata app makes requests and those ports?
Thanks

I attach more details of the system

I did a test by removing the proxy from the netdata.conf file. and I get these errors:

2023-11-03 17:28:20: netdata ERROR : ACLK_MAIN : Failed to connect to '54.198.178.11', port '443' (errno 111, Connection refused)

but if I put it in the .conf file
[nube]
proxy = http://************:8080

something new?
thank you

Same problem.

Sniffer shows HTTP CONNECT message without “Host” header. Nginx proxy reply 400 “Bad Request”.

Netdata agent MUST include Host header in CONNECT request message.

Fix please.

@ars hey, thanks. Fixed in Include the Host in the HTTP header by stelfrag · Pull Request #17670 · netdata/netdata · GitHub.

@ilyam8 hey, another problem after checks v1.45.5

CONNECT to app.netdata.cloud is correct now. Thanks!
But CONNECT to mqtt.netdata.cloud not fixed :frowning:

Thanks for reporting it @ars , we confirm the issue and are working on a fix Include the Host in the HTTP header (mqtt) by stelfrag · Pull Request #17731 · netdata/netdata · GitHub

The mentioned PR is merged and the fix is available on the latest nightly release.
