Connection problem between ap or 5g/ap

Hi

Everytime i change from one ap to another on the same local network or from wifi to 5g or reverse, the app loses connection and gives me the option or wait or add another address. Waiting doesnt do anything.
If i disable wifi and turn it back on, the app works again.

Only having this issue with ha app.

Anybody knows why this is happening?

Anybody can help with this?
