File found when accessing from one server, but not another

From one machine:

╰─>$ upspin get f@filmar.us/work/fin/.git/refs/heads/master
upspin: get: client.Get: f@filmar.us/work/fin/.git/refs/heads/master: item does not exist:
        store/storecache.Get "096AB46A96AC269CB28CE51FC8EAA358F3DF481656DD391EC1FBC93C0A380BC7":
        store/server.Get:

Server-side log:

2019/04/24 07:41:08.734319 rpc/storeserver: "f@filmar.us": store.Get("096AB46A96AC269CB28CE51FC8EAA358F3DF481656DD391EC1FBC93C0A380BC7")

(no error is shown, apparently)

From another:

╰─>$ upspin get f@filmar.us/work/fin/.git/refs/heads/master
d67d2af59c6083c4f9301f676744ffe07d30c5f7

Worth noting that the second upspin get leaves no trace on the server
And:

╰─>$ upspin info f@filmar.us/work/fin/.git/refs/heads/master

Both machines agree on getref, though.

╰─>$ upspin getref f@filmar.us/work/fin/.git/refs/heads/master
upspin: getref: store/storecache.Get "f@filmar.us/work/fin/.git/refs/heads/master": item does not exist:

Are you using a cacheserver in one place and not in another?

[filmil]

Both configurations use cacheserver.

Have you tried removing ~/upspin/$USER/*cache?
