Multi-arch builds suddenly failing

Builds now only work building linux/amd64, but not any other architectures

Drone log:
https://drone.modem7.com/modem7/DHCP-Relay/13
https://drone.modem7.com/modem7/hastebin/12
https://drone.modem7.com/modem7/hddtemp-docker/18/

.Drone.yml:
hastebin (DHCP-Relay)
hastebin (Hastebin)
hastebin (HDDTemp)

Dockerfiles:
hastebin (DHCP-Relay)
hastebin (Hastebin)
hastebin (HDDTemp)

These were working a couple of days ago, but unsure what may have happened to have them stop working. Unfortunately quite new with Drone, so apologies if it’s a glaring ID10T issue!
