Nagios Support Forum

The token field is empty. That's the field ncpa uses for authentication. Can I give you some good advice? You'd be doing yourself a huge favor if you dig into the documentation on their website. For just about anything you need to do, there's plenty of info.

Did adding the token resolve your issue?

Hello,

i never use the token field, leave it empty.
I can try to add.

Firewall is already disabled

Same meesage with token.

Hi, I have the same issue,

[XXX@XXXX ~]$ /usr/local/nagios/libexec/check_ncpa.py -H **** -t ***** -M disk -l
UNKNOWN: An error occurred connecting to API. (Connection error: '[Errno 104] Connection reset by peer')

with nmap the port is open

5693/tcp open rbsystem

$ curl -v https://****:5693

you have any solution?

Are you able to connect to the NCPA client with a browser? i.e., go to https://ip address:5693/?

Ignore the ssl warning that will appear, and use your token to log in.

Hello,

on my side, it was a firewall dropping the flow, even if i catched it using telnet.
