Attachment and Saved Reply Issue

[SecureCPU]

I started getting this issue today.

Every time I try to attach a file to an email or every time I try to use saved replies and add a link to the file I'm trying to attach.

I tried uninstalling and reinstalling saved replies. It helped for one email. Then started having the same issue again.
I tried the same with extended attachments, but it didn't make a difference

I checked the logs but can't seem to find anything.

I do see this error, idk if its related.

Can you reproduce the issue on https://demo.freescout.net/ ?

[SecureCPU]

no.
I ran sudo chown -R www-data:www-data /var/www/html but that doesn't help. and everything shows as good on the system status page

[SecureCPU]

So I found out that it has to do with a file size limit.
files that are only a couple KB, work. but anything larger doesn't

any idea how to fix that?

I've increased PHP size limit dramatically to PHP upload_max_filesize / post_max_size | 100M / 100M but that didn't help

[SecureCPU]

update.
So i can upload differnt type of files.
i can upload .txt .json but I can't upload .pdf .docx .png or anything else.
i tried changing a .docx extension manually to .txt but that didn't help.

so now I'm very confused.

i have a suspicion this started happening after I update the linux server by running the command: sudo apt update && sudo apt upgrade

This is what the server is currently running:

App Version: 1.8.51
Web Server: nginx/1.18.0
PHP Version: PHP 8.1.2-1ubuntu2.9

Also, I can't seem to be able to paste things into the email.

For example, if I just type it's fine.

But if I paste then I start getting a pop-up saying Error occurred. Please check your internet connection and try again. that keeps popping up every 5 seconds until I refresh the page

I think I found the Issue,
Doing a little testing. Will update as soon as I confirm

I believe I found the issue.

For anyone using cloudflare, Security > WAF > Managed Rules > Cloudflare OWASP Core Ruleset <<< keep this off. When turned on, it started giving my FreeScout a bunch of issues and disconnecting my connection until I refreshed the page.

One of my guys turned it on a last week, turned it off, and now it seems to have cleared up the issues.
