Can't connect to cloud when trying to claim node

Node claiming fails with a problem connecting to

Failed to connect to, return code 60
Connection attempt 1 failed. Retry in 1s.
Failed to connect to, return code 60
Connection attempt 2 failed. Retry in 2s.
Failed to connect to, return code 60
Connection attempt 3 failed. Retry in 3s.

The node is on Linode and from there I cannot ping and a traceroute hangs up on an akamai node. Perhaps this is normal ICMP blocking for security.

The netdata clound is an AWS ingress point:

❯ dig

And if I tshark the connection I do see an expired certificate alert. Could that be the problem?

338 9.957636811 → TLSv1.2 73 Alert (Level: Fatal, Description: Certificate Expired)

Ah wait, maybe it’s a certificate problem on the NODE side! This is a node that for for idiotic reasons has not been updated in a while.

You are not alone with this problem. Problem is that ~middle 2021, Let’s Encrypt changed their certificate chain. Because of that many systems that are not updated often enough faced the problem of not trusting our current certificate. Your machine does not trust us because path of certification is not trusted for it.

But just to be sure I checked our and it looks healthy:

openssl s_client -connect | openssl x509 -noout -dates
depth=2 C = US, O = Internet Security Research Group, CN = ISRG Root X1
verify return:1
depth=1 C = US, O = Let's Encrypt, CN = R3
verify return:1
depth=0 CN =
verify return:1

Have a nice day

Thanks for confirming that is the issue @Mateusz_Bularz. We actually have a thread on the forum about that, so @nedludd please check this thread Certificate verification error connecting to the cloud

Hope you get it sorted out.
