Doesn't load on iOS Safari

[kommen]

Going to https://mapcomplete.org/benches.html on iOS Safari

Results in the message: A problem repeatedly occurred on "https://mapcomplete.org/benches.html"

iOS Version 17.4.1, iPhone 15 Pro

I've had some issues too today, I think there were some issues with Github pages. Does it still occur? Does https://hosted.mapcomplete.org/ work as it should?

[kommen]

@pietervdvn thank you for the quick reply!

Unfortunately it still occurs. Tested in private browsing mode as well as in normal browsing mode and also with content blockers disabled. Sometimes it does work a bit, but as soon as I zoom in or then want to add a feature it crashes again (see further screenshots below)

Also https://hosted.mapcomplete.org doesn't work, it returns and blank page with no content.

Let me know if there is anything I should try or any logs I can provide to investigate.

To https://hosted.mapcomplete.org

It is just empty for me with a content-length of 0:

I cannot reproduce this (but I don't have access to an iOs-device right away).

I have to admit that this behaviour is quite weird and I'm suspecting internet troubles. Did it work before on those devices? Does it work with a different internet connection (switch from WiFi to cellular or vice-versa) Does it work on a different (non-Apple) device?

If you have a macbook @kommen , trying it on Safari on there might be an interesting debugging step

It looks likely it is a network related issue. Using the 4G connection on my iPhone doesn't cause the trouble, but I had it on two different Wifi networks. I don't have the problem on the same Wifi networks with my MacBook...

Anyway, closing this for now as it seems it is not a general issue. I will report back if I find more actionable details.

Someone had the same issue with the binoculars-theme, but the playgrounds theme worked as expected on their phone on the same network.
