I’m experiencing build errors and extremely slow context build.

```auto

Error: failed to fetch an image or build from source: error building: failed to solve: rpc error: code = Canceled desc = grpc: the client connection is closing

```

Seems to be the same issue I experienced back in December:

[https://community.fly.io/t/extremely-slow-docker-builds/17183/8](https://community.fly.io/t/extremely-slow-docker-builds/17183/8)

Edit:

I’ve deleted the builder but nothing has changed.

The context seems to be transferring at like 30-50 kBps.

It’s not my connection… Just did a speed test and got 150Mbps upload.

Edit:

Getting other errors now

> Error: failed to fetch an image or build from source: error building: failed to receive status: rpc error: code = Unknown desc = no such job ydhv7frvv6vnwcmbqkl18flt4

And

> WARN Failed to start remote builder heartbeat: failed building options: failed probing “personal”: read tcp [fdaa:0:24d2:a7b:8eb7:0:a:400]:26411-\>[fdaa:0:24d2::3]:53: i/o timeout
