I will take a closer look at the issue once I’m back from vacation. What I found in the server logs 'til yet was not very conclusive, except some errors coming from the Lemmy side (but I can’t say if they are the real reason).
Best of luck - I hope you’re able to help people get to the bottom of what’s going wrong.
Unfortunately, my experiences with reporting federation problems in the past has often been that it’s hard for me to get the right info to the right people.
I hear you. I’m not sure where kbin admins are, but I think it’s hosted in Germany. I don’t know if time zones are a factor, since I have no idea where .ml is hosted or where admins reside, for either instance. @blued_gear
