Volumio.local and IP Address doesn't work on iPad

Hi All, I know there’s a couple of other posts about getting volumio.local to resolve on an iPad and they haven’t worked.

I had volumio.local working on all my devices (PC, iPhone and iPad) until my wifi router was restared (Fritzbox). Now my PC and iPhone can resolve volumio.local and/or the IP adress - the iPad can’t. I’ve tried all the browsers and the volumio app but my iPad can’t connect to either the bonjour address or the IP. I also did a erase and reset - no difference. I’m completely stumped.
