I cannot run the OMV 6 PhotoPrism PlugIn.

Hello, PhotoPrism is not working despite all my attempts for 2 days. When I click Open UI it waits for a while and gives an error "Page loading problem". Connection timed out. The server 192.168.1.222 takes too long to respond.

My system is OMV 6. I did all the updates first through System|Update Management and then via Putty with the apt update and apt upgrade commands. I then installed docker and portainer with omv-extras. After these processes, I restarted the system and installed the PhotoPrism PlugIn that way.
"The location where to store the application data." I changed the directory twice. I still can't run it and I can't figure out where I went wrong. All I know about Linux are the ls, cd, rm, apt update and apt upgrade commands.
All images of my system are attached.
I translated this text into English with Google Translate. I seek your understanding for errors.

Hello,
When I tried again this evening, it started working even though I didn't make any settings changes. It is currently adding the photos I uploaded to the library to try.
I guessed that Portainer and Docker were not needed, but I thought they would be needed for additional programs like Emby, which is my next target, so I installed it. They are now empty.
Thank you very much for your interest and concern.
Best regards...
