Hello. I’m unable to upload videos, even files as small as 2MB. It says “This file is too large.” How can I resolve this issue?

You need to update app.yml too.

I don’t understand how to complete this step because I access the server via the ispmanager panel.
1. **Save your changes:**
- Press `Ctrl+X` to exit, then `Y` to confirm, and `Enter` to save the changes.
1. **Rebuild the Discourse instance:**
- Run the following command in the `/var/discourse` directory:
```plaintext
./launcher rebuild app
```
1. **Update site settings:**
- Go to the `/admin/site_settings/category/files` section in the Discourse admin panel.
- Change `max attachment size kb` and `max image size kb` to your desired size (e.g., `20 MB`). In the settings interface, you can enter a value and select the unit of measurement (KB, MB, or GB) from the dropdown list.
❗ Both parameters are limited by the nginx `client_max_body_size` value, which is controlled by the `upload_size` parameter set in step 3. Site settings cannot exceed this limit.

You need ssh access via the terminal.

I decided to increase the maximum file upload size myself.
What can be done now?

Do you mean to repeat everything from scratch? Everything according to the instructions?
- Run the following command in the `/var/discourse` directory:
```plaintext
./launcher rebuild app

Who can help restore the forum? I can send server access credentials via private message. I put so much effort into creating the forum (and broke everything.
