Official Bitwarden Android App connection failure

Hi Everyone,
my recent problem on importing passwords using JSON format has been solved (the whole server required a restart not only the docker or lxc container). But now I wanted to set up the android bitwarden app on my phone and the ios bitwarden on my wifes phone, but both phones say, they cannot connect to the server. Same configurations for the browser plugin in chrome and firefox on the computer are working fine, only the mobile phone apps cannot connect, even if they are connected to the same network.
I am running Docker in a LXC container on proxmox and bitwarden is running inside a docker container.
The bitwarden instance does not use a reverse proxy with a domain and a certificate, since synicing data while being home is sufficient for us.
I use “https://LocalServerIP” as the server url which works fine for the browser plugins. The mobile phone apps through “Exception message: Connection failure”
Thanks in advance for your expertise.

Hi. I have the same issue with our self-hosted server with the difference, iOS is working fine but we get the message “Exception message: Connection failure” direct after fill out and safe the information for the self hosting url.

Hi i have the problem but for me IOs is not working but the Chrome plugin is. Where you able to fix it by now?
