#86 POST and GET errors with mastodont.cat on GNUSocial 1.20.9

Hi, i got some logs from mastodont.cat sysadmin regarding federation issues with gnusocial.net:

• /api/subscriptions and /api/salmon fail with 404:

[06/Nov/2019:10:59:28 +0100] "POST /api/subscriptions/106511 HTTP/1.0" 404 28 "-" "GNU social/1.20.9-release (The Invicta Crusade)" [06/Nov/2019:11:44:03 +0100] "POST /api/salmon/1 HTTP/1.0" 401 0 "-" "GNU social/1.20.9-release (The Invicta Crusade)" [06/Nov/2019:11:44:03 +0100] "POST /api/salmon/1 HTTP/1.0" 500 856 "-" "GNU social/1.20.9-release (The Invicta Crusade)"

• GET petitions to /users/some_user DO work, but not the ones to /api/users/show.json:

[06/Nov/2019:11:32:59 +0100] "GET /api/users/show.json?id=spla HTTP/1.0" 404 0 "-" "GNU social/1.20.9-release (The Invicta Crusade)"

• He tried from matriu.cat (same version as gnusocial.net) and it worked:

[06/Nov/2019:12:12:59 +0100] "POST /api/subscriptions/88155 HTTP/1.0" 200 0 "-" "GNU social/1.20.9-release (The Invicta Crusade)"

Is there anything I can do to debug this?

gnusocial.net is using 2.0-dev where this behaviour is corrected. Closing!
