Searching Volumio via local wifi .... :-(

Hi. Everyday, once or twice, my iPhone looses connection with Volumio. They are both in local wifi network, network is working on all devices, IP address in Volumio Settings, in iPhone is also correct. It happens so often, that I am thinking to say goodbye to you guys and switch to Roopie XL/ Roon for example. Please help

How are you connecting to Volumio? With the app? Or browser? Are you connecting directly to the Volumio hotspot?

In my case it connects right away or I restart the app and it works. Never loses connection.
