Please describe the issue you are seeing.
I have a /strange/ issue with the 3rd Party client Tapestry.
Sometimes I receive an HTTP 421 Error message. It is not really consistent and I see not really any pattern to it. The Developer of the app says that he doesn't do anything special and I'm the first one to report this issue.
According to the HTTP Error code, it "indicates that the request was directed to a server that is not able to produce a response".
Maybe it’s some combination of special configuration on Hachyderm and this app? Missing Headers?
I think it first happened a few months back.
I have some timestamps when this happened (all times UTC+2; Europe/Vienna)
13.4.2026, 12:40:51,865 [WARNING] Action error
| Error performing action 'boost': Error: 421 response is invalid
Or this
13.4.2026, 12:39:38,389 [WARNING] @Mpwg@hachyderm.io (org.joinmastodon)
| Error: 421 response is invalid

How long have you noticed this issue?
a view months back
What geographic region are you accessing Hachyderm from?
Vienna, Austria, Europe
Is there anything else that we should know?
As far as I know, this happens only on my iPhone with Tapestry (both on the latest versions)
