[Bug]: Agent Registration via Key Fails about netdata

[ilyam8]

Hi, @AlphaOmega2020. You need to provide more info:

• How did you install Netdata?
• We need buildinfo. It is /opt/netdata/usr/sbin/netdata -W buildinfo. The path may be different, you can find it using ps faxu | grep [n]etdata.

[AlphaOmega2020]

• /opt/netdata/usr/sbin/netdata -W buildinfo

@AlphaOmega2020 is it possible for you to use the latest version of Netdata? There are have been some changes in the claiming process and the latest Netdata may work out of the box.

What to do if it still does not work?

You have 2 options:

1. Use the claiming script directly (from the console) to see the full error report. The Linux system you use seems pretty old and there may be issues all over the place. I can provide instructions on how to do this.

2. Use any other Netdata as a Parent. So, edit stream.conf (in both servers) and push the metrics of this Netdata to the other Netdata, that is already claimed to Netdata Cloud. This way, this Netdata will appear in the cloud dashboards.

Which method you prefer?

[daNutzzzzz]

Hi,

Thanks for the response, im happy to try both options, starting with number one first.

[AlphaOmega2020]

FYI im now on v1.45 and same issue

[ilyam8]

it pauses for a fee seconds then gives the "unknown http error response" response

Netdata logs a message when failing to claim, did you happen to check the logs?

Try executing the claiming script directly:

cd /opt/netdata/usr/sbin/
# become netdata user
sudo su -s /bin/bash netdata
# execute the script, add your token
VERBOSE=1 ./netdata-claim.sh -token=TOKEN -url=https://app.netdata.cloud

Apologies for the late response.

Its failing with the same response in GUI

Failed to claim node with the following error message:"Unknown HTTP error message"

I ran some basic connectivity tests:

[/] # ping app.netdata.cloud
PING app.netdata.cloud (44.196.50.41): 56 data bytes

[/] # curl app.netdata.cloud:443
curl: (52) Empty reply from server

I get the same connectivity results on servers that do connect.

@AlphaOmega2020 this issue seems similar (or maybe the same) as reported on this thread, could you check the last 2 posts and see if it helps?

I think @hugovalente-pm is correct. Unfortunately, there is nothing we can do if the certificates on your system have expired. Check the link to find out how to fix the problem.
