Go to Settings → System → Network → IPv4

Check your DNS server setting. Try 1.1.1.1 or 8.8.8.8

Thanks so much, but it didnot work and seems this is a docker Hub mirro issue? after looking it up on chatGDP, but not pretty sure.

Tom’s right.

Context deadline exceeded could be a network or DNS issue. Or because the Docker engine lacks resources (memory or disk space).

Do you have enough resources in your Home Assistant itself ? aarch64 means it is ARM based. Is this a Pi ?
