webviews within hotwire native app seem to break after upgrading kamal-proxy

[34code]

upgraded to latest kamal proxy and get the following screen on all links now when pointed to "remote". Localhost seems to work fine inside simulator.

Same issue when simulator is pointed to "remote". Here are some logs..

[34code]

some additional logs

[joemasilotti]

What version of iOS are you running?

What do your sever logs report?

[34code]

I'm running iOS 18 in the simulator and 18.2 beta on device. Looking at server logs in production now..

[34code]

Production logs when loading the app from simulator show the following:

I have a GET /fp which is fired by JS on page load to detect browser fingerprints of users for tackling fraud and bot activity..

[34code]

Should I show the kamal-proxy logs as well?

[34code]

[34code]

I'm also on MacOS Sequoia Public Beta.. This could potentially be a reason.

[34code]

seems like localhost is also not working anymore.. hence i feel like this might be unrelated to kamal-proxy and a macOS beta issue with Xcode.

[34code]

nvm. I upgraded the OS to developer beta (Version 15.2 Beta (24C5079e)) and the simulator started working again.. going to check remote on sim and then close this issue..

[34code]

Ok its working again! I think it was some issue with the networking stack on the public beta..
