mastodon 4.2.7 Unable to follow service-provided actors (bookmarks@domain)

[ganyuanmen]

I cloned the project, running in the https environment, the website used normally.
get:
https://nngym.site/.well-known/webfinger? resource=acct:bookmarks@nngym.site
Return:
{ "subject": "acct:bookmarks@nngym.site", "links": [ { "rel": "self", "type": "application/activity+json", "href": "https://nngym.site/u/bookmarks" } ] }

get https://nngym.site/u/bookmarks can returns json results. But in mastodon 4.2.7, I couldn't find bookmarks@nngym.site.

I don't know if this is related, but I'm getting SSL errors when I go to https://nngym.site/u/bookmarks

I am currently seeing connection failure / is the site down?

I haven’t dug in on the Mastodon changes 4.2.3->4.2.7 but I do think Postmarks has not always worked as expected for me with the webfinger lookups. Something for us to look into.

Yes, I turned off the service yesterday, and now it's on.

curl -H 'Accept: application/ld+json; profile="https://www.w3.org/ns/activitystreams"' https://nngym.site/u/bookmarks

return:

}

But,on mastodon4.2.7 can not look up "bookmarks@nngym.site"

Oh my god,
before return profile activity, you must add the following command :
res.setHeader('content-type', 'application/activity+json; charset=utf-8');
the old version of mastodon is not necessary, but the new version of mastodon must do this,This is puzzling.

This makes sense in the context of recent CVEs, thank you @ganyuanmen for identifying it.

Feel free to submit a Pull Request!
