Apart from Dokku, there's coolify and caprover.

Happens to the best of us! localhost or 127.0.0.1 should work too.

Cloudflare tunnel only requires outbound port opened, check if you've allowed all outbound ports in EC2 security group (the default VPC should have this already).

Otherwise it's probably a misconfiguration reaching the IP/port of the cloudflared service on the EC2. Have you tried checking cloudflared logs? Does your tunnel status show up as healthy?

Just FYI, your account shows up as a bot. You should change it in your account settings.

Yeah. I guess we could fetch all image ids from the database excluding those uploaded to our local instance, and loop them through the DELETE /image/delete/{delete_token}/{file} API. But I've no idea how to get the delete_token, seems like it's available only during image upload.

I was talking about the storage space on server, not on the user side! Sorry if I wasn't clear.

Doesn't look like there's a way to clean it manually right now, so buckle up!

There is an API DELETE /internal/variants in pictrs to clear out variants of generated images. However it only cleared out a few megabytes in our case.
