[BUG] Duplicate notifications to new client before restart

[Yukigamine]

Describe the bug
After adding a new client, push notifications to that client are duplicated until the igotify assistant container is restarted. After a restart, the new client only gets one push notification as normal.

Expected behavior
I expect the system to process a new client and then only send one copy of each notification to the device rather than two.

Screenshots
Container logs:

Container database:

Smartphone (please complete the following information):

• Device: iPhone 15 Pro Max
• OS: iOS 26.1
• Version of Container: 1.5.0.1
• Version of iGotify: 1.5.4 (41)

Additional context
Saw this issue was related to #84 and did some digging.

Removing the instance in the app and re-adding did not work, nor did uninstalling and reinstalling the app.

When I looked in the logs and saw that the client only seemed to register once, but the application responded twice, I checked the database and confirmed that only one entry for this client existed.

So I tried restarting the container, and after the restart, I only get one notification on the newly added client.

Ok thx for the hint, I will take a look at it and try to fix it in the next update

Same here - Was just about to open an issue....
Thanks for your work!

Hi @Yukigamine, I am currently investigating this problem.

Can you please help me with a test?
Can you reproduce this error? When yes, try to add some random data in the Custom Headers section of the instance and save it. Is the problem gone after adding the Custom Header information? When yes, perfect, I can use the reconnect procedure from the function there :)

I ask because I can't reproduce it. I’ve tried it so many times now, but no luck. My system is running smoothly 😅

[Yukigamine]

What data should I add in the custom header?

The issue is very consistent on my system and has been easy to reproduce.

Add something like for the header "Test" and for the value "Im the Test" and select Gotify as Endpoint

I'm having the same issue here. I always receive duplicate notifications, however when I open the app, I only see one. Also, the duplicate notification does not use the custom app image set in Gotify. Perhaps this could be a clue? Thank you for the amazing app by the way! :)

No can't underline that. They had the same icons for me...

After I removed the -TZ Parameter from my docker compose it stopped with the double notifications...

Thx for the answers @Makario1337 and @SwadeDotExe ,
@Makario1337 yeah the reason for that is the restart of the container and new building of the connections to gotify via the Websocket.

That's the reason why i ask about adding the a random Custom Header over the app to the container workflow.
Because there i kill all the connections and make a rebuild of them, like a restart of the container.
When this work i can fix it easily.

[SwadeDotExe]

I apologize, where can I specify this custom header? I do not see any environment variables I can set for this.

[androidseb25]

@SwadeDotExe Instance -> press on the instance -> Edit Instance -> scroll down -> Custom Headers -> and there you can add it

Add something like for the header "Test" and for the value "Im the Test" and select Gotify as Endpoint

Sorry for the delay, but I tried adding exactly that as the header and selected Gotify as the endpoint.

Immediately following, there was a disconnect error in the logs, and then when I try to send a test notification, I'm no longer getting pushes at all.

For good measure, I started with a clean users.db and client connection, verifying that I was getting the double-pushes beforehand.

For what it's worth, I then removed the custom header and still not getting a connection.

[SwadeDotExe]

That is odd, I was able to specify a custom header and that seems to have done the trick! Before doing the custom header, I reinstalled the app and verified I was still getting duplicate notifications. After setting a dummy header and restarting the app, I only get one notification. Thank for the advice @androidseb25!

is the database really cleared?
Because you have one Done in it or is every clienttoken the some in the log?

@SwadeDotExe yeah cool, when it works then i think it is the way i go. I will wait with the release until the problem by @Yukigamine is fixed.
