I have set up Umbrel on my Raspberry pi 4 and is 100% Synchronized which up to date has a block size of 391GB.
I have left it connected to the Internet & I have installed mempool app from the App section.
When I go to query an bitcoin address balance on mempool page, It says - [ Error loading address data.
Error: Connection to server lost, please retry ]
Please help me out. Is there anything should I do?
