Http errors can't upload for submissions

Hi, I’m using OJS 3.1.1.4. Everything was working fine but recently I just can’t upload files for submissions.
It happens too with the Quick Submit Plugin as well as regular submissions.
I already tried to disable plugins and nothing.

I found this on the console:
consola

And here’s the error log:

Hello @Ana,

The version of OJS that you’re using is no longer supported by PKP. I recommend that you upgrade to the newest version of OJS, as it is possible that your issue will be resolved by upgrading (although that’s not guaranteed). However, other community members may wish to offer assistance.

Upgrading instructions are available in the PKP Administrator’s Guide.

Information about the latest version of OJS can be found on the PKP Website

Best regards,

Roger
