Error uploading images

Is there someone with this error? When trying to upload images, I'm having a "R2 upload network error" message. At least from my Android cellphone.

Right now using Brave browser, cleared cache, checked site permissions, app updated, tested from the web app and the site.

Tried to upload a picture right here. No luck.

EDIT: Maybe not related but in case someone finds it. Possible data exceeding on Cloudflare maybe?: https://stackoverflow.com/questions/72378177/error-network-connection-lost-saving-form-data-file-to-r2-bucket
