Discourse moved from [sub1.domain1.com](http://sub1.domain1.com) to [sub2.domain2.com](http://sub2.domain2.com). Links etc seem ok, I can log in with the admin account, but I can’t do it with Discourse ID. I tried removing that Discourse from my Discourse ID list to “start fresh” but it’s still not working. When I click on “log in with Discourse ID” I get this:

Any suggestions for how to fix this?
