Android App fails to upload over domain - Web works fine

I've got a fresh installation which works great, except for the mobile app over my subdomain. The web interface works and uploads just fine over the domain on other networks.

The only oddity I see in the logs is

HttpException(400): {"message":"Multipart: Unexpected end of form","error":"Bad Request","statusCode":400}

What’s your proxy and network stack? Cloudflare?

NAKCityOP•4/15/25, 5:21 PM

Cloudflared

Zeus•4/15/25, 5:21 PM

You’ll have to disable whatever they’re doing to chunk/break up the file. Immich doesn’t support it

NAKCityOP•4/15/25, 5:25 PM

Any idea if that's done server side or on the CF daemon?

Zeus•4/15/25, 5:31 PM

Not sure, I assume on their web login but I have no idea

NAKCityOP•4/15/25, 5:36 PM

In case someone comes across this:

Cloudflare -> Zero Trust -> Networks -> Tunnels -> (Your hostname - NOT subdomain) -> Configure -> Additional application settings -> HTTP Settings -> Disable Chunked Encoding

NAKCityOP•4/15/25, 5:45 PM

Unfortunately, it still fails. I see a notification saying the upload is 100% complete, then it disappears and says failed.

Same message on the server logs, nothing interesting in app logs.

All services were restarted after the CF change

Zeus•4/15/25, 5:45 PM

is the file over 100MB?

NAKCityOP•4/15/25, 5:45 PM

No. I actually made a small 500KB file to test

NAKCityOP•4/15/25, 5:47 PM

NAKCityOP•4/15/25, 5:48 PM

It still works fine over the web interface on my phone's cellular network or over the local ip wifi switch-over

I'll let it sit in case it takes time for the changes to propagate.

NAKCityOP•4/15/25, 6:17 PM

Still nothing. I logged the proxied requests from Android and Chrome and there are some key differences:

Android:

Sorry, you can wait some hours to see if it propagates, and then reach out to cloudflare since it’s an issue on their end

Ok, thanks @Zeus

Catorze•4/15/25, 9:27 PM

@NAKCity im having the same problem

Catorze•4/15/25, 9:27 PM

all day trying to upload from app, using CF proxy

Catorze•4/15/25, 9:28 PM

most of them get 100%, but random files stuck on 100%, and none of them is on immich after

Swirley•4/16/25, 2:02 AM

experiencing the same issue here. setting the network to detect the local WiFi and configuring the server LAN IP completely alleviates the issue.

Swirley•4/16/25, 2:02 AM

doesnt do you any good away from home, but narrows the issue down a little

Me too, I have the same problem.

TyroonBlack•4/16/25, 8:10 AM

Hey there! I am facing the same issue. I have two immich instances in two separate networks and locations, both served via CF tunnels. The upload via mobile app (both ios and android) stopped working, if I try to manually upload a picture via the app, i get the "failed" message. Moreover, an upload via web interface on the browser, with the subdomains, works fine.

Yoko•4/16/25, 1:34 PM

Same issue on iOS app here. Switched out of cloudflare for the moment.

phantom0174•4/16/25, 4:58 PM

same issue here, but only on Android (works fine for iOS and web)

NNAKCity Ok, thanks @Zeus

BuraG•4/16/25, 5:05 PM

Any progress on your search?

Swirley•4/16/25, 5:35 PM

not a solution, but i turned off the tunnel and configured nginx for the time being.

Catorze•4/16/25, 6:52 PM

which version of server are you using? A friend of mine, using server 1.130.1 dont have the issue, im using 1.131.3 and having issues with backup using CF proxy
