Download and Email Report not working

Hello
We have recently done some work on our offline Nagios system recently to try to get more security and use from our system.
I had a problem recently to do with the reports when we were at 5.5.3 that could download the reports but the emails were corrupted. This was resolved.
We upgraded it to use SSL with our own windows CA. I have followed the instructions given and eventually had success. Main issue to this for me was with Google Chrome needing an alternate subject name, I thought this had been removed from the latest version, but no.
I have recently upgraded to 5.5.5 and done the yum updates to ensure it is current.
My current problem is to do with reports again, I am finding the downloaded reports are showing up as per the availability pdf attached and the email reports are corrupted.
Thanks
Terry

Hello,
@tpwebb. This looks like a possible SSL misconfiguration.
Try running the first command on the terminal while generating the avaliability report PDF in the GUI. Copy all the errors to this forum thread. Then repeat the same with the second command.
tail -f /var/log/httpd/error_log
tail -f /var/log/httpd/ssl_error_log
Also, please check the external URL under Admin/System settings in XI.

Hello @npolovenko
Thanks for your reply
I have attached the availability report in the attachments, after trying to sort out any SSL issues found in the logs I now get a 'Session Timeout' error on the emails and the download of the reports.
Running the report with tail -f /var/log/httpd/error_log
Code: Select all
[root@nagios ~]# tail -f /var/log/httpd/error_log

@tpwebb, Please open the /etc/php.ini and double the session.gc_maxlifetime value. Then run:
service httpd restart
In XI web interface go to the Admin menu, then click on System Settings in the left column, click on the Security tab and make sure that:
Keep session alive while interface is open, even if user is inactive.
Is checked and also double the "Session Timeout" value.
Let me know if this fixes your problem.

@tpwebb, Please go to the Admin menu in XI, then click on System Settings in the left column and make sure the the program URL and external URL fields are filled out.
Please go over this tutorial to make sure SSL is configured correctly:
https://assets.nagios.com/downloads/nag ... s%20XI.pdf
Are you able to see reports normally in the web interface?

The internal and external are matching. I had the second blank as there is no external web address but have now made them matching.
It was these instructions that I followed and have checked this again, as far as I can see it is working.
I have also noticed that the downloaded graphs in png format are getting cropped.
I have changed the setting for the internal web page to http and now I am getting the default home page so I must have something wrong, unsure.
Thanks

@tpwebb, Please open the following file in a text editor:
/usr/local/nagiosxi/html/config.inc.php
And add the following option:
$cfg['old_browser_compat'] = 1;
You can change the URL back to HTTPS.
Let me know if this gets the reports to work.
