Can not connect to Flutterhole

[Rot10Crotch]

I sent this to your gmail address but the reply indicated this was a better place to submit issues. So this is a duplicate of that message.

Describe the bug
I installed flutterhole on Saturday July 11, 2021. At that time I was running Android 11 on my Samsiung S10e and Flutterhole worked fine. On Tuesday July 13, 2021, I applied an Android update to my phone. Since then Flutterhole has not worked. I have tried uninstalling/reinstalling it and deleting my Pihole settings and resetting them. I keep getting a message "fetchVersions failed _$MalformedResponsePiException" I do not recall changing anything on my Pihole.

Do you have any suggestions as to how to get it working again?

See above.

Expected behavior
Access to the Flutterhole dashboard on my Pihole server.

Versions (please complete the following information):

• Pi-hole version: 5.3.1

Additional context
my setup is

The router is an ASUS RT-AC5300 running Merlin firmware V RT-AC5300_386.2_6

Edit: I can not ping my RPI 3b from my phone. all other devices (Windows, Linux, & Android) can ping the the RPi 3b. However, I can SSH into my RPI 3b from my phone.

Hi Rot10Crotch, thank you for opening an issue!

"_$MalformedResponsePiException" typically indicates that the API response from your Pi-hole does not match the expected format. This is likely due to an update in the Pi-hole API. If you feel inclined, you can look through the app's query logs to inspect which requests are failing.

The app runs on a somewhat outdated version of Flutter, so chances are the error is not on your end. A new version of the app is in the works, with (hopefully) better error reporting.
