App Version 3.2.0 crashes up on connect to any server

[miaukatzewau]

Hello Guys,

i found your project yesterday and had to install it on my k3s cluster immediately :)
No issues there, i can access the WebUI just fine.

Problem:
The iOS app crashes up on connect to any grocy server including the demo instances.
For my own Server. i created the access token and then used the QR code for the app configuration. But i also tried manually adding the server and copy&pasting the token. I also tried running the server with auth disabled.
I tried https://myserver.mydomain/api and without /api.

iOS Devices and Versions:

• Iphone air (ios 26.2)
• ipad mini 7 (ipadOS 26.2)

Grocy Versions:

• 4.4.2
• 4.5.0
• demo instances i assume 4.5.0?

I found the following in the app.log the after i started the app again (it auto-closed on connect):
Jan 21, 2026 at 10:11:34 AM: Not logged in Jan 21, 2026 at 10:11:37 AM: Getting timestamp failed.

In the nginx logs in the pod i can see that the ios client is connecting:
root@grocy-6b8fff94bf-chpxv:/config/log# tail -f nginx/access.log 10.42.3.5 - - [21/Jan/2026:16:11:13 +0000] "GET /api/system/info HTTP/1.1" 200 307 "-" "Grocy%20Mobile/50 CFNetwork/3860.300.31 Darwin/25.2.0" 10.42.3.5 - - [21/Jan/2026:16:11:15 +0000] "GET /api/system/db-changed-time HTTP/1.1" 200 49 "-" "Grocy%20Mobile/50 CFNetwork/3860.300.31 Darwin/25.2.0" 10.42.3.5 - - [21/Jan/2026:16:11:17 +0000] "GET /api/user HTTP/1.1" 200 169 "-" "Grocy%20Mobile/50 CFNetwork/3860.300.31 Darwin/25.2.0"

Since the problem occurs also with the demo servers, i assume my setup is not the reason for this issue.
I also just tested the Android App which works with my server. I know its not the same app all i wanted to know is, if my setup is the problem

Can you guys help me with this issue?
Am i doing something wrong?

This seems strange. The NGINX access log looks good (returned data for multiple endpoints with code 200).
And the demo servers work correctly for all users, even the Apple AppStore reviewers.

The error seems like a non-complete setup, where no base URL was set.

Can you please post a log for connection with the demo server?

Thanks for your reply!

I just deleted the app from my iphone and installed it again.
I did not touch anything and directly clicked on "Demo Server".
The result is the same, the app closes, i reopen it an gather this log:

Edit:
I just reinstalled the app again and noticed that this error is in the logfile even if i don't connect to anything. I am so confused that this is happening to my iphone and ipad while others have no problem. Whats different on my devices?

[supergeorg]

Have you tried accessing it with another network, maybe mobile data? I have just spun up a new iOS simulator where the app was not run before, and this problem didn't occur.

[miaukatzewau]

Thanks for the help :)

Yes i tried from mobile services and from my wifi.
Both devices, same behavior.

I found this crash report, i don't know if it helps but i will attach it anyway.

I actually installed the app first yesterday before i even touched the server setup.
I went straight for the demo (like i did in the web) and had the same issue.

I thought its temporary and will solve on its own but apparently not.
I am out of ideas. I tried a lot of things.

As i am writing i tested another device. An old iphone 11 with iOS 26.2 installed. And it works, demo server, my own installation, everything. I don't understand whats up with my iphone air and ipad mini 7...

[miaukatzewau]

I found the issue.

If you set your time format to am/pm instead of 24h the app crashes instantly.
Thats why it only happened on my devices and not on devices not connect to my apple id.
I also just tested it on the Iphone 11 where it worked yesterday. As soon as i toggle off 24h time, the app crashes.

I should have thought about this a lot sooner. I mean it literally says: Getting timestamp failed.

Thank you! :)
