Accessing our public annex via HTTP (http://annex.softwareheritage.org) times out.
Behind the scenes, it turns out that what times out is accessing the relevant nfs (auto)mount on pergamon (/srv/softwareheritage/annex/annexroot), which is exported by uffizi.
The relevant filesystem is fine on uffizi, but nfs-kernel-server there has relevant log entries:
dic 08 17:16:10 uffizi rpc.mountd: refused mount request from 192.168.200.4 for /srv/softwareheritage/objects (/): not exported
(yep, this is for a different export, but I suspect it's related)
