CHECK_VMWARE_API.PL CRITICAL - Host "" does not exist

Hello,
I'm facing an issue while using the plugin check_vmware_api.pl .
As it is visible in the error it says that the Host does not exist.
/usr/local/nagios/libexec/check_vmware_api.pl -H myvmware01 -f "/usr/local/nagiosxi/etc/components/vmware/myvmware01_auth.txt" -l "CPU"
Use of uninitialized value in concatenation (.) or string at /usr/local/nagios/libexec/check_vmware_api.pl line 957.
CHECK_VMWARE_API.PL CRITICAL - Host "" does not exist
The DNS is okay and the host exist, so any ideas what could be the problem?
Thanks in advance.

ping myvmware01
Run the check command using the IP instead of the hostname.

Thanks for the comment Gormank,
I tried it but it still does not work.
#ping myvmware01

#CHECK_VMWARE_API.PL CRITICAL - Host "" does not exist
The strange here is that I have another host where it works perfectly.
#ping myvmware02

Maybe try running on a host that doesn't exist and see what the error is?
Try logging into the nonworking host using the uname/passwd from the file?
You know it works on the one host, so it would seem to be an issue in myvmware01.
Finally, have a look at check_vmware_api.pl around line 957 and a bit above to see why you're seeing "uninitialized value in concatenation" at that point.
