400 The computed checksum does not match #31235
Comments
GitMate.io thinks the contributor most likely able to help you is @PVince81. Possibly related issues are #11811 (Compute and store file checksums on the fly / file integrity), #28584 (ChunkingNG: Intermittently at MOVE, checksums of individual chunks are computed(?)), #19761 (Unauthorised code doesn't match documentation.), #27920 (Home folder unavailable after upgrade til version 10), and #30751 ([files_antivirus] Upload of Eicar throws Sabre\Exception\UnsupportedMediaType). |
Can you manually compare the MD5 / SHA256 checksum of the file as it appears on the data folder with the one from the upload ? Maybe try uploading a text file bigger than 1 MB (ex: log file) and see if you can identify what kind of corruption it is having. In general this sounds more like an environment issue, something that is interfering with the data stream. |
MD5 seems to be ok on each side... It seems that it occurs less often anyway so you must be right when you says that is environment issue... I'll keep an eye on it today... @PVince81 : is it possible to give you an ssh access to give a check to our instance if necessary ? Thx ! |
@Crush33 please see https://owncloud.org/help/ for support as this seems to be an environment issue and not a bug in ownCloud. |
After long investigation you were right. After this, the upload seems ok for every clients. Conclusion : Better install owncloud server on debian headless... |
I had a similar (likely not exactly the same) issue. I got errors "400 The computed checksum does not match the one received from the client", too. Setup: ownCloud running inside debian guest in VirtualBox, ownCloud Desktop Client running on a debian maschine. I figured out that the problem was on the client side! The problem and solution was simple: I had a not working, to high, network MTU setting on my client computer (MTU 1500). Solution for me was: sudo ifconfig eth0 mtu 1492 (exchange eth0 by the network adapter name, make permanent MTU change later if this works out) that solved the problem for me. I hope to be helping someone else who might be experiencing the same problem. |
Hi
I got a very very nasty issue right now on one of my owncloud server.
Every client (windows 10 mostly running client v2.4.1) got a "Connection Closed" after trying to upload any file bigger than 1MB.
Owncloud is running on Debian 9 virtualized on winserv 2016 and everything was running fine until my last apt update / upgrade a few days ago.
The error in owncloud.log is : "400 The computed checksum does not match the one received from the client." And i really don't know why this is happening...
Note : i run a "shrink" operation on my owncloud virtual hard disk which is running in HyperV which i can explain more in details if necessary.
Steps to reproduce
Expected behaviour
Upload correctly the files

after a few sec "Connection Closed" message appears on the client and upload fail.
