Umbrel ios has lost support for raspberry pi 4?

Hi,

first of all sorry for my english.

I did an umbrel ios server on a raspberry pi 4 in order to have a bitcoin node. It has been running of for months but I usually don’t look at it, it it simply just turn on.

Today I have tried to access to it and it seems to be down, however, there is ping

I have search for the last umbrel ios version but now, I can not find a version for raspberry pi 4, just for raspberry pi 5

¿is it umbre ios out of service for raspberry pi 4?

Greetings
