No sync without validated Internet connection

[nutpantz]

No validated internet connectivity
Synchronisation may not run.

I am using a local network with no internet.
And I don't seem to get a sync to work.

I can set up and connect to the server but that is it.
Does this app require internet for no real reason? It is waiting for something that will never happen before syncing over lan?

Is not creating a calendar that I can find with etar or fossify calendar. Decsync creates them fine.

The answer is it WILL not sync.
It requires internet. Which it should not. So i filled a bug report

Hi, have you tried the VPN connectivity option in the account settings?

[nutpantz]

when i am not using a vpn? no

it does not appear to help if i turn it on..

i can create calendars, create accounts all without internet connectivity (verified), but i cant sync..
because Android’s [WorkManager] requires internet to do anything. which requires it connect to google first.
which is silly. and if google goes down or is blocked, nothing works.
( lets not even talk about how many people want to get away from google and come here for that)

You probably already know this, but while we would like to support syncing without a validated internet connection, the problem is that we would need to wake up the system to make a connectivitiy check ourselves, eventually draining battery unnecessarily.

Usually people can sync with their own server in their own LAN just fine, when they allow their phone to reach the internet.

It's true that we could support this special use case with an extra setting, which when enabled, would allow synchronization without validated internet. It's not planned at the moment however.

Please also see @rfc2822 answer in this discussion: #363 (reply in thread)

[rfc2822]

All said - we'd like to support it (#990), but it's not supported at the moment and there's no specific time when we have this ready.

So make sure there's a validated Internet connection until then (or provide a good PR, of course).

It's btw mentioned in https://manual.davx5.com/settings.html#synchronization under "VPN", but there should be a better place.

How about supporting it with manual syncing? Then it will not wake up the device and cause battery drain.
Connecting to the server and creating an account all work without internet. Pretty silly to demand it just to sync.

And you should change the warning to "we will do nothing without internet validated by google"

There may be ways to do it properly and not just on manual syncs, but we need to think about it in debth. Right now, for the majority of users everything works as intended. It's not silly at all and pretentious nagging won't make us work on a solution any sooner.
