403 access denied during uploading file

[tvio]

Hello,.
During uploading file/attachment bigger than 10MB, I get response 403. I can`t upload bigger attachment. Smaller files uploading correctly. Problem isn`t saved in log file ./data/logs
I don't know where a restriction is set.
The problem also occurs for the zip attachment with Espo system update.


Does anyone know how to solve this problem?
Thank you for help!

Hi,
It looks like this error returned by your server, not EspoCRM system.
Anyway, enable DEBUG mod as it described here https://docs.espocrm.com/administrat...e-for-a-logger and try to upload the file again. After receiving an error, investigate the log file again.

[espcrm]

By the way, how are you uploading this? Is it through Email attachment? Documents? Or a new field you made?

Does this error happen to all or just one?

Based on my experience there is a few reason why you may get that error:
1) Server restriction by file types or file size.
2) Timeout of server or EspoCRM (not enough time to upload all data).
3) Unstable internet connection, internet get cut off.
4) Slow upload speed resulting in timeout.
5) File permission error (cross this out since you can upload smaller)

By the way, have you tried the infamous or (wow I didn't expect that to work method?). Clear cache and rebuild, then refresh page (F5).
