500 Internal Server Error when Agent send a ticket reply.

chunheng

[1] When an Agent send a reply to a ticket, the Agent may be hit with Error 500:

500 Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at webmaster@xxx.com to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

When the Agent refresh the page, the ticket does have the Agent reply in the ticket.

[2] When the Agent called the User, the User said they did not receive any email about a ticket reply from the Agent.

When the Admin check the System log, there are no error system message for Sunday at 4:00pm - 5:00pm UTC+8.

For reference, this is the information of the support ticket.

I am not sure which files I should request from my host provider. Please advise.

500 is a generic server error indicating a deeper issue. You need to check your PHP error logs and webserver error logs for related errors.

Cheers.

How does the Agent "send" the reply?

Discussed with the host provider.
The memory limit of the server is raised and error log is turned on from host provider side for the server.
I am now waiting for the reoccurrence of the error 500 issue in live environment so there is an error log to read.

Through the Post Reply tab on the bottom of a ticket and then press Post Reply.

A typical reply usually either consists of text-only or text with inline images (range from 1 to 10) or text with file attachments (below email limits of 10 MB, usually in .pdf or .zip format).

I have never recommend the Agent team to reply through email as sometimes the email was not ingested into the osticket system even with proper ticket number given and correct osticket email receiver.

chunheng

At the moment, I am being led to believe by the host provider support that it is an email provider issue, which is working for beyond 6 years of service.

Additionally, the host provider support asked me for Google side to install OAuth2 plugin and setup Google - OAuth2 authentication in place of Basic Authentication (Legacy) with App Password (which has been working for a while): https://docs.osticket.com/en/latest/OAuth2/Google%20Authorization%20Guide.html (which requires setting up the plugin manually from fresh install: https://docs.osticket.com/en/latest/Guides/OAuth2%20Guide.html ; For my reference, this is for Agents: https://docs.osticket.com/en/latest/OAuth2/Google%20Authentication%20(SSO)%20Guide.html ; Users side will requires me to go through business orders to lobby Google to acknowledge the business which is too much effort and not a priority considering bulk of our userbase is on Microsoft or on some custom self-service mail servers).

I am asking the host provider for the error log again as I also have a separate error of Resource Limit Is Reached on top of rogue error 500.

KevinTheJedi

chunheng

Hmmm...odd. If you are using Gmail you really should migrate to OAuth2 because there is no telling when legacy auth/app passwords will be permanently retired/disabled. However I can't imagine why it would cause a "Resource Limit is Reached" error. I was originally thinking it was taking too long to connect to the mailserver and it was timing out but this is a different error. But maybe it is related; I won't know for sure until we get an actual error from the logs.

Cheers.

We need the PHP error logs.

Cheers.

KevinTheJedi

chunheng

Also, idk how that's the relevant logs when you're running osTicket v1.18.2 and PHP 8.2; the logs you provided shows application/x-httpd-ea-php72 which is PHP 7.2 so these don't appear to be related.

Cheers.

chunheng

KevinTheJedi
I am on shared host plan so the PHP 7.2 is apparently coming from the host's web server.

The log given was extracted from the hosting's Apache's error log.
As the hosting's Apache is natively using PHP version 7.2, hence it has shown on the log as 7.2.

As I am using cPanel, the host support notified me to do the settings either from the osTicket (if available) or cPanel.
For reference, this is php.ini:

; cPanel-generated php ini directives, do not edit
; Manual editing of this file may result in unexpected behavior.
; To make changes to this file, use the cPanel MultiPHP INI Editor (Home >> Software >> MultiPHP INI Editor)
; For more information, read our documentation (https://go.cpanel.net/EA4ModifyINI)

allow_url_fopen = Off
allow_url_include = Off
display_errors = On
enable_dl = Off
error_log = "{ERRORLOGPATH}"
file_uploads = On
max_execution_time = 30
max_input_time = 60
max_input_vars = 1000
memory_limit = 128M
post_max_size = 8M
session.gc_maxlifetime = 1440
session.save_path = "/var/cpanel/php/sessions/ea-php72"
upload_max_filesize = 20M
zlib.output_compression = Off

Opening up the cPanel's MultiPHP INI Editor's Basic Mode:

Summoning GeminiAI wisdom, I manually added in a line through Editor Mode: log_errors = On

Now to another game of waiting for the error to trigger, this time from osTicket.

KevinTheJedi

chunheng

Typically with shared hosts and cpanel you have error logs in the site directory and even sometimes in subdirectories.

Cheers.

chunheng

My team sent me this on last Friday when I was on leave:

Checking the php.ini:

When I checked the cPanel's File Manager:

I am trying to find out with the host provider why the php_error not erroring to the file path or I am typing the error_log path wrong (support is a directory/folder, not a filename).

KevinTheJedi

chunheng

Usually it's called error_log or example_domain_com.php.error.log (where example_domain_com is your actual domain).

Cheers.

chunheng

KevinTheJedi

Posting here for my sanity sake:
example_domain_com.php.error.log:

Located at: /logs/
Last updated: 17/03/2025

error_log:

Located at: /public_html/example_domain_com/scp/ and /public_html/example_domain_com/api/
Last updated: There's like four domain folders here. I am checking it individually now to see which one have latest error_log.

chunheng

Digging through the install history, the osticket was last updated from v1.15 to v1.18 at 20250316.

The latest log I found is: /public_html/example_domain_com/api/error_log (every few minutes there's error happening here). This was from designated email to create ticket sync work and run by cron as per: https://docs.osticket.com/en/latest/Getting%20Started/Email%20Piping.html.
The rest of the error_log are all outdated with the latest one from /public_html/example_domain_com/scp/error_log is dated 20210228, which is not useful.

Below here a censored trimmed (because the actual log is 70 MB starting from 20210408) copy of the /public_html/example_domain_com/api/error_log:

Previously:

display_errors = On

Now updated the php.ini:

display_errors = Off
display_startup_errors = Off
error_reporting = E_ALL

Now my personally custom-named error log is actually created:

Cross-checking on the details of the two domains and crontab, I might have been using the Email Piping to an ancient version of osTicket.

Updated the crontab to use the newer version's cron script.

You should upgrade to v1.18.2 for sure if you have not yet done so. That'll stop all the deprecations warnings, etc.
Have you found a related error yet? The ones you posted above are either irrelevant notices or irrelevant errors in regards to posting a reply.

Cheers.
