Claude Studio v1.18.2
When the secure version will not open
The setup page can now test the secure connection and say what actually happened, instead of leaving you with "it does not work". The same answer is written to the Mac's bridge log, so it can be read afterwards.
It also names the trap that looks like a bug: if that address is already installed on the Home Screen, Android hands the link to the installed app — which opens with no address bar and reads exactly like "it opened the plain version". Chrome then offers no Install entry either, because there is nothing left to install. Remove the icon and install again.
Typing the address by hand needs the port (:7443); the page prints it.
