Getting 404, on some sizes of images

[nilsmakeable]

We are seeing {"status": "error", "code": 404, "message": "The hostname of the origin is unresolvable (DNS) or blocked by policy." } On requests on some image sizes. If we change the image size the image appears as expected.

In the nginx error.log on we see the following lines

• [error] 7#0: wrong ident 51546 in DNS response for firebasestorage.googleapis.com, expect 61389
• [error] 7#0: wrong ident 56714 in DNS response for firebasestorage.googleapis.com, expect 19598
• [error] 7#0: wrong ident 24211 in DNS response for firebasestorage.googleapis.com, expect 24813
• [error] 7#0: wrong ident 24632 in DNS response for firebasestorage.googleapis.com, expect 7164
• [error] 7#0: wrong ident 41805 in DNS response for firebasestorage.googleapis.com, expect 61819
• [error] 7#0: wrong ident 38646 in DNS response for firebasestorage.googleapis.com, expect 38720

This issue seems a bit above my experience with nginx, any pointers would be appreciated.

Sounds like the DNS server is not properly configured. Is this with Docker? If so, see: https://github.com/weserv/images/issues/206#issuecomment-1752740666.

@nilsmakeable Were you able to make any progress with this?

@kleisauke It was in docker, but it was configured correctly, and I had seen the above mentioned thread earlier.

I ended up adding a default url on the script generation our urls with a cache break parameter to avoid the intermittend errors. since then we haven't seen any problems. Which means I haven't been given any more time to look into a better / more correct solution.
