context deadline exceeded is back :/

I can no longer build using the remote builder, it always fails with:
Error failed to fetch an image or build from source: error connecting to docker: failed building options: failed probing “umi”: context deadline exceeded

The builder name is fly-builder-floral-water-2397

Resetting the builder and Wireguard connections has no effect.

This used to be caused by the slow propagation of wireguard peers … but Fly fixed that. Hmm.

It may be a temporary issue Fly will be aware of and be fixing, however it’s worth seeing if using websockets on their CLI helps. Just in case it’s a network issue at your end that’s blocking the default UDP:

fly version update (get the latest version, or however you prefer to do that)
fly wireguard websockets enable
fly deploy (or the command you want to run)

Any improvement?

If not, what does the fly doctor report?

You were right, my university’s network was disrupting the connection.
