Xiaomi Bridge binding keeps getting removed


I am currently installing my Xiaomi bridge to link some temperature sensors throughout the house.
However, I cannot get my Xiaomi bridge to work. Everything works fine in the Xiaomi Home app.
But my bridge won’t show up in OpenHab. This is what I get in my logs:

2019-06-16 09:43:55.334 [thome.event.ExtensionEvent] - Extension 'binding-mihome' has been installed.
2019-06-16 09:43:55.731 [hingStatusInfoChangedEvent] - 'mihome:bridge:23b57bfe' changed from UNINITIALIZED to INITIALIZING
2019-06-16 09:48:55.791 [hingStatusInfoChangedEvent] - 'mihome:bridge:23b57bfe' changed from INITIALIZING to OFFLINE

When I reboot my openhab system it removes the binding.

2019-06-16 10:01:38.850 [INFO ] [core.karaf.internal.FeatureInstaller] - Uninstalled 'openhab-binding-mihome'
2019-06-16 10:01:38.867 [thome.event.ExtensionEvent] - Extension 'binding-mihome' has been uninstalled.

What I have tried so far:

  • Rebooting the system multiple times
  • Adding the bridge manually, but then it just says “Offline”. It cannot find the bridge by itself.
  • Adding port 9898 to my firewalls whitelist
