FST error every 10 seconds: "cannot send report broadcast"

We seem to get these errors on FSTs pretty regularly every 10 seconds, running EOS 5.4.1:

Not sure what report, where it is broadcasting to, or why it failed.
How can I fix it?

Thanks!

It seems to have been related to a SSS authentication problem from the FSTs to the MGMs.
