I’d like to ask about a technical issue regarding Discourse’s support for Amazon S3 storage. I came across a forum post from as early as 2013 that already discussed Discourse’s S3 support. I also found a few threads related to CDN offloading, but there doesn’t seem to be much detailed information o…

If your friend had followed Configure an S3 compatible object storage provider for uploads you’d not see enable_s3_uploads. It’s unclear whether setting those in the database rather than ENV is part of the problem. That’s not the same as Enable direct S3 uploads . That’s “Enable direct S3 uploads” …

[이미지] wenqin: video files still cannot be uploaded to S3 storage. What happens instead? Do you get an error message? You might also want to check the settings “max attachment size kb” and “authorized extensions”, both in Site Settings - Files. Please note that even with CDN and S3, this se…

[16b8a6fac1f5401ab6793f8e1fa0b4c9] [image] Thank you very much for your reply. Here’s the situation: Right now, images from my forum can be successfully uploaded to S3, but videos cannot. It’s really confusing to me. Although I understand that S3 might still not be ideal for handling videos, th…

You forgot to answer my question :slight_smile: [이미지] wenqin: but videos cannot. It’s really confusing to me. [이미지] RGJ: What happens instead? Do you get an error message?

[이미지] wenqin: I didn’t consider using a CDN because of cost concerns—Amazon S3’s CDN service can be quite expensive. Amazon’s CDN is cheaper than egress from S3 buckets. You definitely want a CDN in front of your S3 bucket. I suspect that the error you haven’t told us about has to do with vi…

[image] When I try to upload a video to my forum, it now directly shows the message: “Sorry, that file is too big (maximum size is 50 MB). Why not upload your large file to a cloud sharing service, then paste the link?” However, my video itself is only 10 MB. Currently, I’m using S3 storage with…

Hello, thank you for your reply. I have already asked my friend to switch from the S+ storage with proxy caching method to the S3 storage + CloudFront CDN delivery method. However, it seems to have failed, and I don’t know the reason yet. So I was wondering if you could provide the exact execution …

[image] Hello. Actually, here’s the situation: Videos smaller than 10MB can be uploaded to my own server, but the video files themselves cannot be uploaded to S3. When uploading a video, the system automatically captures the first frame as the thumbnail, and the thumbnail image can be uploaded t…

[이미지] pfaffman: But I changed my max upload to 100MB and tried to uplaod a 37MB file and got the “file is too big” error, so you may be right that there is a bug. Did you change it in app.yml too? [이미지] Change the maximum attachment/upload size Self-Hosting …

Thank you very much for all your help. He said he had followed the instructions in Configure an S3 compatible object storage provider for uploads , but it didn’t work. However, just now, after he did the same as you suggested and changed the maximum upload file size to 100MB, the video was successf…

They should probably be participating in this topic, then. Did they follow Configure an S3 compatible object storage provider for uploads and put the setttings in the ymll file and add the part that pushes assets to S3?

Maybe the browser somehow isn’t communicating the size appropriately.

Did you try this?
