NAGIOSQL LOGIN FAILED!

===================
INSTALLATION ERROR!
===================
Installation step failed - exiting.
Check for error messages in the install log (install.log).

If you require assistance in resolving the issue, please include install.log
in your communications with Nagios XI technical support.

The script that failed was: './E-importnagiosql'

It looks like there is a proxy server setup of your system and there are some settings that have to be done to get Nagios to function with a proxy.
Take a look at this KB article and see if that fixes your issue.

The no_proxy setting in the /etc/wgetrc file should fix the error.

Resolved by the KB. I did not put in the no_proxy=Localhost.

That is good news that the issue is fixed now. Shall I close and lock the post as solved for you?

Yes issue is resolved.
