[Bug] 404 in thumbnail image request fails to close connection

[gummybuns]

Describe the bug

404 on certain thumbnail requests seem to fail to close the http connection

Steps to Reproduce

# 1. notice that the `videoThumbnails` includes a `maxresdefault.jpg`
curl http://<invidious_instance>/api/v1/videos/1gWd-FHfAQE

#2. curl fails to close connection
curl --verbose "http://<invidious_instance>/vi/1gWd-FHfAQE/maxresdefault.jpg"

Logs
Despite the curls failing to close I do see a 404 emitted in the logs

2025-11-25 22:45:50 UTC [info] 404 GET /vi/1gWd-FHfAQE/maxresdefault.jpg 286.86ms

Additional context
Same thing happens in firefox for me for what its worth

docker inspect invidious | grep version
                "com.docker.compose.version": "2.35.1",
                "org.opencontainers.image.version": "2.20250913.0",

I am very new to invidious so feel free to shut me down if i did something dumb in my self hosted solution
