Checked server time, its ok. Cleared browser cache many many times. Rebooted Nagios Server. :roll:

So I cannot resolve this issue. Only on day 5 of using Nagios and nobody can log in owing to this message. Please someone help!!

Hi,

That error is usually related to the time settings. Please post the output of the following commands?

Code: Select all

grep "date.timezone" /etc/php.ini
ls -l /etc/localtime
date 
php -r 'echo date("D M j G:i:s T Y")."\n";'
Also, select F12 for the developer tools, and then try logging in and post a screenshot of the Network Tab. Are you seeing any errors in the status column?

Also, see this output:

will@poc1vm:~$ grep "date.timezone" /etc/php/7.4/cli/php.ini
; http://php.net/date.timezone
;date.timezone = Europe/London
will@poc1vm:~$ grep "date.timezone" /etc/php/7.4/apache2/php.ini
; http://php.net/date.timezone
date.timezone = Europe/London
will@poc1vm:~$

Hi,

Thanks for checking that. The timezone looks good but It's definitely not loading. Do you have any type of security hardening enabled or proxy server setup? Did it ever work when you installed the software?

Is SELinux enabled?

Code: Select all

sestatus
Are you able to curl the server address successfully?

Code: Select all

curl -k -L -v https://<server-ip-address/

Hi,

Okay so I have found that if I clear my browser cache, I can get in.

However this maybe only stays OK for a day. Yesterday I could log in ok. This morning I could not, got the message. So I cleared the cache and now I can get in.

So it is related to cookies?

See output:

Normally, you shouldn't be seeing this messages so often. At the end of the day, do you log out or put your computer to sleep? If you do, this would mean that you are trying to re-submit a form with the wrong info. This is not an error that we see often at all in support, so it has to be something unique to your environment or the way you log in/out of Nagios XI.
