@akavel@merveilles.town I mean if you open the home page of your blog from a normal browser (any browser, mobile or desktop) do you still see the certificate error? If that's not the case and you have a split domain configuration (so your blog is on a URL and your federated domain is on another) then double-check that both the certificates are valid.

@fabio Oh I didn't install your blog on my host yet! For now I wanted to comment/fave in _your_ blog and I couldn't do that - this is my problem...

@akavel@merveilles.town oh I see, that sounds weird though, many other people could interact already...could it be that you're in a MITM configuration with some corporate or private VPN injecting SSL certificates at runtime? I have similar issues when I browse from my corporate VPN domains that my VPN hasn't whitelisted yet - then it'll try to inject an invalid certificate

@fabio I _think_ I might need to ask the admins of the instance I'm on - assuming they'll have time and will to debug this. Maybe there's some quarrell between that server and your server. (Which one's at fault is a different matter - may be neither ;P)

@akavel@merveilles.town oh I think I see a potential issue here: https://merveilles.town/@fabio@manganiello.blog

I used to use WriteFreely on that ActivityPub domains before but now it's on Madblog, of course with a different signing key.

I see that your instance still cached some old posts of mine from the time the blog was on WriteFreely, but I can't search for new URLs.

I think that something off is happening on your instance because I can see that the cached version of my blog profile has now the updated profile fields (so it accepted the updates from my blog), but the latest cached post is from 2024 (and I've written more since then, both on WriteFreely and Madblog) and it can't find new ones.
