[ErfolgreichCharismatisch]

Describe the bug
I got 206, -9003 then 003, -9003 then Data Submission Error on the android smartphone

To Reproduce
Steps to reproduce the behavior:
I downloaded the certificates installed them on my phone(without root).

I used for server ip 127.0.0.1 and I started it with

sudo pipenv run python -m bumper --listen 127.0.0.1 --announce 127.0.0.1

I got

[2021-10-20 18:30:16,280] :: INFO :: bumper :: Starting Bumper
[2021-10-20 18:30:16,357] :: INFO :: mqttserver :: Starting MQTT Server at 127.0.0.1:8883

[2021-10-20 18:30:16,398] :: INFO :: mqttserver :: Bumper Authentication Success - Helperbot: helperbot@bumper/helperbot

With the bot being switched off(!)

I switched it on, ran sudo pipenv run python -m bumper --listen 127.0.0.1 --announce 127.0.0.1 again and got the same output.

I connected to raspap with my Android and then ran the app.

I got 206, -9003 then 003, -9003 then Data Submission Error.

Expected behavior
No error messages, normal functionality without internet access.
