Error (return code) 60 when trying to claim code when trying to connect node with cloud service

Hi Team,

When I am trying to claim a node it fails with return code 60.
Failed to connect to https://app.netdata.cloud, return code 60

Connection attempt 3 failed. Retry in 3s.
grep: /var/lib/netdata/cloud.d/tmpout.txt: No such file or directory
grep: /var/lib/netdata/cloud.d/tmpout.txt: No such file or directory
Failed to claim node with the following error message:"Unknown HTTP error message"

Also I noticed, 2 files are missing in the cloud.d files:
claimed_id
cloud.conf

Tried running the netdata-claim.sh
It throws a token error.

Problem/Question

What I expected to happen

Can you check if it’s due to Certificate verification error connecting to the cloud ?
