ERROR 413 when uploading a file - no log entries

[murugappan]

Hi,

We just hit a unique problem. In the accounts entity we have a field called "Support Documents" of type multi-attachments. All this while, from 2018 until 2nd November 2025, we had no problems. Then we started to get Error 413 when we upload any file larger that 500KB. The limits in CRM, SERVER and PHP has been set 128MB. When we checked the crm and server logs and there are no entries.

Any idea what could be the problem area? Any assistance will be appreciated.
