Lemmy federation: missing properties field

Hi All,

I’ve setup my lemmy server and I can join communities at other servers without problems, but not for some servers. In the log I can see this error when searching for a community:

</span>

What can I do to fix that? I’m running 0.17.4, installed with lemmy-Easy-Deploy and, as said, I can subscribe to communities on a couple different servers without problem.
