Help needed for ipcamera binding

I need some help for my esp32 cam.

I am using this modul

and I can access the stream by using this link http://ipaddress/stream

this is my configuration

Thing ipcamera:generic:Esp32Cam
    ipAddress="ipaddress", serverPort=54322,
    ffmpegInputOptions="-f mjpeg",
    ffmpegOutput="/tmp/Esp32Camera/", ffmpegInput="http://ipaddress/stream"

But I always get this error:

Thing 'ipcamera:generic:Esp32Cam' changed from INITIALIZING to OFFLINE (COMMUNICATION_ERROR): Connection Timeout: Check your IP and PORT are correct and the camera can be reached.

how can I check what is wrong exactly??
