Description
Dear *!
I m using Nginx to cache video files, which are delivered via http1.1 from a Java based backend Application.
Unfortunately, I am facing problems to request the final slice at the end of the video file from Nginx via byte range requests.
With the following curl command I m facing always connection resets triggered by Nginx.
curl -v -I -X GET http://localhost:8080/APInoauth/storage/VX-1/file/VX-106339/0.9395159304006587/VX-106339.mp4 -H 'range: bytes=342130688-342300277'
Curl output:
* Expire in 0 ms for 6 (transfer 0x560dda43b7a0) * Expire in 1 ms for 1 (transfer 0x560dda43b7a0) * Expire in 0 ms for 1 (transfer 0x560dda43b7a0) * Expire in 1 ms for 1 (transfer 0x560dda43b7a0) * Expire in 0 ms for 1 (transfer 0x560dda43b7a0) * Expire in 0 ms for 1 (transfer 0x560dda43b7a0) * Expire in 1 ms for 1 (transfer 0x560dda43b7a0) * Expire in 0 ms for 1 (transfer 0x560dda43b7a0) * Expire in 0 ms for 1 (transfer 0x560dda43b7a0) * Expire in 1 ms for 1 (transfer 0x560dda43b7a0) * Expire in 0 ms for 1 (transfer 0x560dda43b7a0) * Expire in 0 ms for 1 (transfer 0x560dda43b7a0) * Expire in 0 ms for 1 (transfer 0x560dda43b7a0) * Trying ::1... * TCP_NODELAY set * Expire in 150000 ms for 3 (transfer 0x560dda43b7a0) * Expire in 200 ms for 4 (transfer 0x560dda43b7a0) * connect to ::1 port 8080 failed: Connection refused * Trying 127.0.0.1... * TCP_NODELAY set * Expire in 150000 ms for 3 (transfer 0x560dda43b7a0) * Connected to localhost (127.0.0.1) port 8080 (#0) > GET /APInoauth/storage/VX-1/file/VX-106339/0.9395159304006587/VX-106339.mp4 HTTP/1.1 > Host: localhost:8080 > User-Agent: curl/7.64.0 > Accept: */* > range: bytes=342130688-342300277 > * Empty reply from server * Connection #0 to host localhost left intact curl: (52) Empty reply from server
The Nginx log file show the following error as reason for the reset.
2019/09/24 17:03:13 [debug] 7#7: *6 http slice response range: 341835776-342884352/342300278 2019/09/24 17:03:13 [error] 7#7: *6 unexpected range in slice response: 341835776-342884352 while reading response header from upstream, client: 10.254.5.228, server: , request: "GET /APInoauth/storage/VX-1/file/VX-106339/0.5595379191458786/VX-106339.mp4 HTTP/1.1", upstream: "http://10.253.185.134:8080/APInoauth/storage/VX-1/file/VX-106339/0.5595379191458786/VX-106339.mp4", host: "dev-distribution.ucp.pke.fhm.de"
-> rest of the debug log is attached
In the debug log I can see that the upstream server and Nginx have not the same view regarding the range request values, but actually I dont know which system delivers the correct range values.
It would be great to get some advice in which direction I should try to solve the issue.
