[ssantha1985]

Dear team,

There is a requirement to change the port from 80 to 443 for few UPS devices which am getting this error message
if its port 80 then seeing this output

./check_http -H XXx.xxx.xxx.xxx -L -w 60 -c 120
<A HREF="http://xx.xx.xx.xx:80/" target="_blank">HTTP OK: HTTP/1.1 200 OK - 1961 bytes in 0.147 second response time </A>|time=0.147184s;60.000000;120.000000;0.000000 size=1961B;;;0

./check_http -H xx.xx.xx.xx -p 443 -L -w 60 -c 120
<A HREF="http://xx.xx.xx.xx:443/" target="_blank">HTTP CRITICAL - No data received from host

unable to pull the information and need guidance to update with correct parameter in check_http

Much appreciated if i could get an solution on this.

Hi @ssantha1985,

Port 443 is the default port used for HTTPS (SSL/TLS - enabled) traffic. Your requirement is probably to set up SSL/TLS on your server. Once it is configured, you can use the -S option in the plugin to connect via SSL/TLS.

You may also have to allow port 443 in your firewall.

Let us know if you need any more assistance.

Thank you!

Dear gwesterman,

We are already configured SSL / TSL in our nagios Server and still am using this command to query the UPS devices which are communicating with 443 throwing the error like below.

/usr/lib64/nagios/plugins/check_http -H 10.12.7.245 -p 443 -L -w 60 -c 120 -S
<A HREF="https://10.12.7.245:443/" target="_blank">CRITICAL - Cannot make SSL connection.

I have followed the steps which mentioned here to generate the SSL / TSL certificate

https://support.nagios.com/kb/article/n ... acle_Linux

But still same issues only. much appreciated if i can get a exact steps to sort out the on going issues from nagios server

Thanks & Regards,
Santhanam

Hi @ssantha1985,

I don't think the linked article will help you with check_http - that article is more about configuring an HTTPS certificate for the Nagios Core web interface itself.

If you need a more detailed error, I would run check_http with the -v option - hopefully that will point you in a more useful direction. If you need us to help more directly with troubleshooting, I would open a case on Answer Hub.

Hi @ssantha1985,

I would give some of the options discussed in this thread a try. If none of these work for you, let us know.

Thank you!

Can you navigate to the https url in a browser window? If so do you get a warning about the SSL/TLS certificate being untrusted?
