CRITICAL - Cannot make SSL connection Nagios XI

Postby pbachu2 » Wed Sep 04, 2019 8:44 pm

Hi All,
We have migrated all hosts/services from Nagios Core 4.0.8 to Nagios XI 5.6.3.
Post migration, currently we are working on clearing all critical and Unknown services in XI.

For few hosts we are getting CRITICAL - Cannot make SSL connection errors.

The same configuration in our old Nagios core is working.However it is not working in new nagios xi.

command line in XI:
$USER1$/check_http -H $ARG1$ -C 30,15

Run check command output from GUI :
[nagios@dc1prd484.tower.lan ~]$ /usr/local/nagios/libexec/check_http -H $HOSTADDRESS$ -C 30,15
check_http: Invalid hostname/address - $

[root@ libexec]# ./check_http -H qa1.corrorequest.lan -C 30,15
CRITICAL - Cannot make SSL connection.

Please suggest how to proceed.

Try adding the -S option to your command to connect via SSL. If it does not work, please post any error messages. Thanks.

Code: Select all
./check_http  -S -H qa1.corrorequest.lan -C 30,15
