My impression is that in my case, the problem is not with ssh, but somehow
with the guix daemon. I tend to observe this:

guix offload: sending 1 store item (6,490 MiB) to '141.80.167.169'...
exporting path 
`/gnu/store/y4ipvkapf1gninaabwdl6pcz46c1frak-texlive-texmf-20210325'

Then jnettop shows data transfer of about 100 to 120MB/s during a bit over
a minute, which makes me think that the actual data transfer succeeds, but
that somehow the data is not registered in the store.
Then nothing tangible happens and offloading times out. Since I am
apparently not able to connect to the machines via ssh, I cannot have a
closer look at the receiving end.
