Statistics loading very slowly when using the app

Just a quick random guess: A delay before the actual request is sent sounds to me as if it would be delayed by the DNS resolution (and maybe your primary DNS server has a timeout?).

Thanks for the idea. I've tried and set the Wifi connection to manual configuration, using Google's DNS, but results are the same. Also, shouldn't the mobile browser have the same issue then?

It appears the app is trying to connect to another endpoint before retrieving data from the actual server. The setting "Anonymous tracking" in the app is disabled.

@chris-ca is there maybe some redirect happening? Like from HTTP to HTTPS? Although this should be visible in the apache logs as well. The app is otherwise not connecting to any other endpoint. Weird it works when eg using a VPN.

I'm actually currently in a different network as well where I had issues with a very small number of sites as well and enabling VPN made it fast. I didn't investigate further as it isn't my network/router. I haven't looked into it but it does sound like some network configuration issue. Here maybe 2 suggestions to look at:

• MTU Settings: Maximum Transmission Unit (MTU) determines the maximum size of data packets that can be transmitted over the network. If the MTU value is set too high, it can lead to fragmentation and slower speeds. Try lowering the MTU value on your router to see if it improves the performance of the affected sites.
• Firmware Updates: Check if there are any firmware updates available for your router. Outdated firmware can sometimes cause performance issues. Updating to the latest firmware version may resolve certain compatibility issues and improve overall performance.

I've checked and there's not other request in the Apache log files.

MTU Settings / Firmware Updates

Does the app use a different TCP stack though than the device browser? Because that's the most inexplicable part for me so far. Unfortunately I don't have control of the router so I cannot modify or check its settings.

@chris-ca I'm actually not sure. Does maybe anyone else know?

Yesterday I updated my backup phone (Android 13/LineageOS) to a new nightly for the first time in maybe 3-4 weeks. The issue has disappeared there (now on 20-20230715-nightly-ocean).
My other phone (Android 12/stock) is still facing issues as described above.
Both devices running Matomo app v2.5.2 so it seems indeed like a bug on OS/networking layer.

Thanks for getting back to us @chris-ca Does this mean we can close this issue assuming it's something to do with the device and less with the app itself?

[chris-ca]

Yeah, all things considered this looks more like an OS+networking issue so I don't see what matomo app devs could do here

Thanks @chris-ca
