Opening Attachments - This site can’t be reached - ERR_INVALID_RESPONSE

Truly hoping you can assist. We have had a stable implementation of OSTicket for many years and recently started running into this issues.
80% of tickets can access attachments without any issues.
Certain tickets face the error below:
The webpage at https://*******/file.php?key=tza6q1tc1zxuct-krbevmuhlh_auj-tm&expires=1738800000&signature=4fb5c979718e8b21472c009522aed7343d0050fd might be temporarily down or it may have moved permanently to a new web address.

The PHP Upload Temp file has MULTIPLE TMP files which I assume may be leading to this issue?

Could be possible temp dir issues but not 100% on that. Make sure you add the system temp dir to PHP's open_basedir INI setting and restart the server. You could also ensure the IIS_USR has appropriate permissions to the temp dir.

Cheers.

Additionally, you could check the _file and _file_chunk tables in the database to see if the file exists and if it has data. For the _file record do where key equals tza6q1tc1zxuct-krbevmuhlh_auj-tm and for the _file_chunk record copy the file record's id from the _file table and lookup where file_id equals the id you copied.

Cheers.

Thank you Kevin, checking above now

Hi All. We had issues on the attachment drive - PHP wasn't happy with it being REFS - we recreated to NTFS and reconfigured the rights, all is perfect.

Thanks for your help
