Hi davide.bonicelli,
Was this just happened recently?
Were there any system/OS updated recently as well?
Yes, I noticed that your "phpmailer.log" did not have the date listed.
Are there php modules missing or old? .... (not sure).
Below is an example of my "phpmailer.log":
Code: Select all
[12-07-2020 13:13:57] SMTP Error: The following recipients failed: [email protected]: relay not permitted
(method=smtp;host=smtp.fusemail.net;port=587;security=tls), Referer: admin/testemail.php
First, which version of PHP are you using?
To check, type:
Also, please try (running) getting "timezone" settings in php.ini file and current date (below).
Code: Select all
# php -r "echo date_default_timezone_get();"
# php -r " echo date('Y-m-d H:i:s');"
# php -r " echo gmdate('Y-m-d H:i:s');"
Standard Log Locations can be found in a few different places (below).
Please check those logs and see if there is any issues that might have stood out ... like missing php modules (for example):
Code: Select all
• /usr/local/nagios/var
• /usr/local/nagiosxi/tmp
• /usr/local/nagiosxi/var
• /var/lib
• /var/log
/usr/local/nagios/var/nagios.log
The Nagios Core log, includes checks, notifications, external commands, and events.
This file is rotated daily into the /usr/local/nagios/var/archives folder
