Media file generate a bad path

Dear community,
I'm trying to include a media file in this case a png and I've an error. I'm using this sample

DNS lookup xx.xx.xx.xx (family:4, host:domain) is not allowed. Because, It is private IP address.Código de error: 500

log for nginx - - [13/Dec/2021:15:25:13 +0000] "GET /-/media/get/https/!BELSzuHlZJSOR6TFYhF4TVQfsd$br2W89!qcQuLef$miXS7uu4Y9txj7c/projects/6/forms/start_screen/draft/attachments/hands.png HTTP/1.1" 500 707 "" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.93 Safari/537.36"


I'm reviewing the nginx configuration and the enketo configuration and I don't see this path.
Any idea?
Best and Merry Christmas

I asked a colleague about this. They gave the following response:!BELSzuHlZJSOR6TFYhF4TVQfsd$br2W89!qcQuLef$miXS7uu4Y9txj7c/projects/6/forms/start_screen/draft/attachments/hands.png Exists as a direct URI. That local IP gives me a hint that a host file may have been created to point to a local IP, but the GET from ODK sees it and rejects it as a local address. I have never worked with ODK, so that’s a guess, but I would check DNS and host files on the server.

For example, if I swap it with a different image ( it works fine. Think this is a DNS issue/host file issue.

I think this might fix it. In Enketo, allowPrivateIPAddress is probably set to false (default). The actual error being seen is on like line 54 of

Hi !, Thanks for the feedback, I think we need to change the docker image or I need to change any properties.
