Hi! I checked old posts closed to my problem but didn’t find the solution, so here I am.
I have a WP site (hosted on server A) connected to a Discourse forum (on server B) and acting as a SSO provider for said forum.
I recently changed host for WP (so, to server C —new hosting company) and DNS provider altogether, from Google to Gandi, scrupulously recreating the DNS settings (@ on the new IP, www as a CNAME, and forum on its unchanged IP) ; the forum staying on the server B.
Now WP says connection is broken and I get a curl 6 error (unable to resolve host; unknown error) when trying to publish (I also get a “there’s no admin with firstname.lastname@example.org address” but I figure it’s kinda normal if it’s not connected).
Any clue or idea where to look? I already contacted the new provider to check any firewall setting but they say it’s all clear and I probably should check with the plugin devs.
