Constantly pinging index.php/204 but not auto uploading

[Mazvy]

Clients have enabled auto upload on their devices, the apps are constantly pinging index.php/204 in bursts but not auto uploading anything.

Sometimes the clients do start to upload, but more often then not it requires them to open the app and only then do the files start to transfer over.

Seeing as this pinging is constant and periodic, I assume the background process is working and not put to sleep by Android, however auto uploads are more often than not - not getting through.

/index.php/204 is the path used to check for connectivity to the server, for reference. In turn, that is called every time a file is uploaded.

In summary, the logs are normal and don't mean anything. If autouploads are failing, more details are needed from the app side (logcat would be best).

But more than 9 times out of 10 no files are getting uploaded - the clients just constantly spam /index.php/204 but don't upload anything.

The users in question aren't very tech savvy, and it's been a struggle gettings app logs out of them. Personally I don't have this issue, but I'm seeing this /index.php/204 spam with nothing uploaded from multiple users.

I insist, the index.php/204 is normal. Each app will ping that route every time it tries to upload a file. Your issue has nothing to do with that route. The problem is elsewhere (and I don't know where), and can't know without logs or reproduction steps.

It seems we're not on the same page.

I'm not saying /index.php/204 is an issue. What I'm saying is that clients are constantly pinging /index.php/204 but not auto uploading.

The reason I'm bringing up /index.php/204 spam is that to me it appears as if the Nextcloud Android app service is working fine on their phones as evident by the constant /index.php/204 pinging, however auto uploads are not coming through. In server logs it's a wall of /index.php/204 bursts with no files uploaded.

I'll try to get someone on a dev version of the app to get some logs. I really wish we had some logs in the regular Nextcloud app as this makes troubleshooting with less tech savvy users next to impossible.... I cannot reproduce this issue on my phone - all files are uploaded perfectly and my phone isn't bombarding the server with /index.php/204 bursts.

Please consider this to be changed. I have NC with Android <5 Clients (3.19.1) and there is nothing to sync (meaning no files to upload, no files beeing in use currently).

I have checked Serverlogs: "index.php/204" is pinged 116910 times each day! Sometime 7 times in a row from the same device in the same second. This is unneccessary at all.

So: What is this ping needed for - is it even needed? To ping something only to know if it is there is no reason to do so.

I would expect no pings at all - maybe some syncjob to look for changed files, but even this is unnecessary, while checking for new versions on access should be enough. Also for uploading: Try to upload, thats it, no ping needed.

As this was driving me nuts, i reviewed an changed the code to not ping the server. Maybe someone can check this.

[obel1x]

There may be a new solution for this, check #10448

[AlvaroBrey]

Should be fixed by #10488, or at least greatly alleviated by it
