Adding go-e charger ends with error java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $

Adding a go-e charger (Gemini flex 22 kW, produced 2024 / 01) as a thing ends with a java error.

Expected Behavior

When adding a charger by adding a thing, specifying the IP address, the thing goes online without an error.

Current Behavior

When installing the binding, adding a charger by adding a thing, specifying the IP address (as shown in the go-e App), the thing does not come online:

2024-07-19 21:48:04.520 [INFO ] [ab.event.ThingStatusInfoChangedEvent] - Thing 'goecharger:goe:go-eCharger' changed from OFFLINE (COMMUNICATION_ERROR): java.net.NoRouteToHostException: No route to host to OFFLINE (COMMUNICATION_ERROR): java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $

Possible Solution

Not sure if this has something to do with the problem, but when installing the add-on, the "installing-icon" (in constrast to installing other add-ons) keeps circling forever. When re-loading the binding, it is listed as installed.

Steps to Reproduce (for Bugs)

Install binding
Add go-e thing
Specify IP address as shown in app
Use "1", "2" or as the API-version in the thing-configuration all throw the same error

Context

All other bindings in my openHAB installation work without any problems. WiFi-Repeater is ~1 m away from the charger (WiFi field strength is 100%).
