Bull Wallet and StartOS Mempool

Hello.
Anyone using the Bull Bitcoin mobile wallet and have their own Start9 server running your own instance of Mempool? The wallet app has recently been updated to allow a Custom Mempool Server to be entered rather than using their default server.
I would like to use the StartOS instance I have running on my own server through the mobile wallet, but the Mempool URL creates a .local address that doesn’t seem to work when entered in Bull wallet.
Has anyone got the two working together? Is there something that needs to be done with the syntax of the address to get it to work in Bull wallet?

Are you able to open the mempool UI from the device, via your server’s webpage directly? The reason I ask is because some Android devices seem to have a problem with mDNS in general, so it may not be an issue with the wallet itself. StartOS 0.4.0 replaces mDNS if I’m not mistaken, so this may resolve once the next version is released, if that is the problem. Of course, another thing to confirm is that your device is on the same local network as your server, and that you don’t have a VPN enabled.

You’re response got me thinking.
Yes, the .local mempool URL comes up on my phone (same device as the wallet) while I’m at home on the same LAN as my StartOS server. But if I turn off WiFi and just use cellular data on my phone I can no longer get to the StartOS Mempool URL (.local). I guess that’s the issue right there - the .local URL is not publically available for the Bull Wallet to make use of.

I have to take back my last message… now the .local URL is not loading on my phone’s browser. I’m confused as to whether it ever actually did work or not, but it’s not right now.
