Dropbox sync occasionally returns 504 error on iOS devices #645

reinhart1010 · 2020-11-03T15:27:08Z

Your Environment

Version used: 6.0.1, Web
Operating System and version: iOS 14.1
Desktop Environment:
Browser Name and version: Safari 14.1

Expected Behavior

The Dropbox sync should work fine. I have tested this against the web app on Android (not the ones downloaded from Play Store)

Current Behavior

The app returns Unknown Sync Error: Error: Request failed with Status 504.

Steps to Reproduce (for bugs)

Open the web app on Safari
Add to Home Screen
Go to the app Settings (in PWA) to set up Dropbox sync
Try wait for 30 mins to 1 hour and try to synchronize again

Console Output

Unfortunately, in order to get the console output I need to connect to a Mac device, which I don't have.

Error Log (Desktop only)

reinhart1010 · 2020-11-03T16:15:52Z

Update: This issue seems to only occur when the app wants to update the data from the Dropbox server (Remote). Otherwise, it will work normally

johannesjo · 2020-11-03T17:26:50Z

Hi there! Thanks for digging into this. Does this happen a 100% of time when data is being loaded? Or just sometimes?

EDIT: Well the title says it all. Sorry!

reinhart1010 · 2020-11-04T03:24:47Z

1. When the app is first launched, as long as there are no remote changes, the sync works fine. 2. Otherwise, the error will occur indefinitely. I also suspect that this also affects the Google Drive sync functionality, as I have experience an "Unknown Sync Error: [Object object]" when syncing with Google Drive on iOS, while it does not occur in the web app on Android (I didn't use the native app due to #434).

I tried to reproduce this on Mac OS as I don't have an iPhone available to debug this. Unfortunately, I was unable to do so.

I opened up an issue here:
https://www.dropboxforum.com/t5/Dropbox-API-Support-Feedback/504-when-reading-data/m-p/467507#M23844

I hope they can help us.

…ely for now #645

johannesjo · 2020-11-07T16:02:21Z

A fix for this should be out with the next release and is ready for testing under https://test-app.super-productivity.com/

Could you maybe check there if the problem still occurs?

reinhart1010 · 2020-11-19T01:00:27Z

I am currently planning to test the staging app but it seems there is another layout issue.

johannesjo · 2020-11-19T09:54:22Z

@reinhart1010 should be fixed now.

reinhart1010 · 2020-11-24T11:48:48Z

The layout issue is still reproducible from test-app.super-productivity.com, while the main app.super-productivity.com does not. Already tried resetting the site data from Safari settings.

johannesjo · 2020-11-24T21:36:32Z

Thanks @reinhart1010 at this point the app.super-productivity.com version might have been the more up to date one. I just updated the test... version as well.

reinhart1010 · 2020-11-25T01:41:26Z

I have already tested in 6.1.1 and the issue still persists.

johannesjo · 2020-11-25T18:55:02Z

I have already tested in 6.1.1 and the issue still persists.

the styling issue or the 504 error or both?

reinhart1010 · 2020-11-26T13:22:09Z

The styling issue has been fixed. The 504 error still persists.

reinhart1010 · 2020-12-04T03:49:38Z

Upgrading to 6.1.2 and the issue seems have been fixed. I'll be testing a few more times before closing it as fixed.

reinhart1010 · 2020-12-04T10:39:25Z

However it still fails with 504 (I guess this is still related to the Service Worker). Trying to reconnect after Airplane Mode does not work as well.

johannesjo · 2020-12-04T18:03:05Z

May I ask what version is shown when you navigate to the settings on the mobile app?

Seems like something went wrong.

johannesjo · 2020-12-06T17:12:22Z

Thank you! I tested with a mac book air safari and I am able to reproduce this as well. I know what is causing this (the service worker stuff still seems to be active for mac somehow), but I don't have a fix yet.

reinhart1010 · 2021-03-21T02:16:52Z

So it seems this is a duplicate of angular/angular#37133

WantToLearnJapanese · 2021-08-30T06:41:01Z

This issue happens also on macOS-Safari.

There is a weird behavior with this issue.

For the first sync (use remote), there is no problem.

WantToLearnJapanese · 2021-08-30T06:46:49Z

Just as a workaround, on iOS, we can use "Alook" which do not suffer from the issue. (This is a paid app $0.99)

I am very curious about why Alook works. Aren't all the browsers on iOS just Safari with different skin?

WantToLearnJapanese · 2021-08-31T19:40:48Z

@johannesjo Isn't it weird that there is no problem for the first sync?

johannesjo · 2021-09-03T14:45:42Z

@johannesjo Isn't it weird that there is no problem for the first sync?

Yes, this might have something to do with some caching going on maybe.

ribtoks · 2022-02-12T05:02:04Z

This issue still persists as of today in the web app on latest iPadOS with latest Safari

johannesjo · 2022-02-12T12:51:47Z

Help with this would be welcome! I currently have no iOS devices available to check this.

m4nured · 2022-05-28T09:10:16Z

Hi Johannes,
What kind of iOS device do you need for checking?
I am thinking about supporting this awesome project by sending you a functional iOS-device.
Would be an iPhone 6s which runs the latest iOS but has a non-essential defect okay, like stripes on the display or some other. Then I might look for a device on "Kleinanzeigen" in the next weeks.
Sebastian.

johannesjo · 2022-06-03T15:00:44Z

Hey @m4nured ! This is incredibly kind of you! :) Thank you very much for the offer! It would possibly be very helpful for debugging IOS related issues and an older iphone sounds perfect for the task. If you still would be willing to go down with this (I totally understand if you don't), we can discuss this via email (contact@super-productivity.com).

MikeMorenoDSP · 2022-10-05T21:25:45Z

Also getting this issue (504)
iPhone 12 running iOS 15.5 using Safari and Dropbox.
Going to test if there are more alternatives than "Alook Browser".

eclecticpassions · 2022-12-08T06:47:08Z

I’m on iPad OS 16.1.1, SP 7.12.0, syncing using Dropbox and created an App Shortcut via Safari to quickly access the app via the home screen. Also have the error code: Unknown sync error. Error: Request failed with status code 504. It also works on the first time, but subsequently fails unless I delete all the cache files in Safari settings related to superproductivity.com and restart Safari. Syncing to Dropbox via my Mac OS Catalina and on Android 12 is okay so far.

michaellammers · 2023-01-27T08:35:54Z

Having the same problem, but mainly here to thank you for this great tool. Been in a week and already loving it!

eclecticpassions · 2023-01-27T11:01:46Z

Can confirm A Look Browser works flawlessly on my ipad mini 6.

tiropictor · 2023-05-08T16:02:54Z

can confirm that error is still here, iPad Air 4th gen, iOS 16.2 (20C65), using default browser for PWA added to homescreen, getting "Unknown Sync Error: Error: Request failed with status code 504"

(Super Productivity v7.13.2)

Other two devices (Android, using app from f-Droid, and Mac, using mac app downloaded from GitHub) sync perfectly.

ITCMA · 2023-06-11T11:15:24Z

Can also confirm error "Unknown Sync Error: Error: Request failed with status code 504" on iOS 16.5 with iPhone 14 Pro and iPad Gen 8. Tested with Chrome, Safari and Firefox Browser. Super Productivity Version v7.13.2.

macOS Ventura (App Store Version - not the Browser) syncing without any problem. If i try it with Chrome on macOS i see the same error 504.
