Trouble Uploading Large Files via WebDAV on Nextcloud Installed on TrueNAS: Need Help Increasing Upload Limits

I installed Nextcloud on TrueNAS using the native TrueNAS app. However, when uploading a large file via WebDAV, it doesn’t allow it. Smaller files upload normally. I tried increasing the upload limits through the app’s graphical interface, but it didn’t work and I still face limitations for large files. If anyone can help, I would appreciate it.
