Trouble posting and commenting from Friendica

Hello,

Over the last one or two weeks, I have had difficulties with commenting from nerdica.net to lemmy.ml (I checked that nerdica.net appears in the federated instance list).

More precisely, my posts and comments don't appear spontaneously, but only appear when I search them by hand in the Lemmy searchbar. In case it helps locating the problem, it appear that these manually fetched post don't have the automatic selflike.

See for example this test post

Thanks in avance for any help :)
