Can't federate with matrix.org, can federate with everyone else

This issue was originally created by @TheStranjer at matrix-org/dendrite#3279.

Background information

• Dendrite version or git SHA: fd11e65a9d113839177f9f7a32af328a0292b195
• SQLite3 or Postgres?: Postgres
• Running in Docker?: No
• go version: go version go1.19.8 linux/amd64
• Client used (if applicable):

Description

• What is the problem: Will federate with every instance except matrix.org, which insists the requests sent use an invalid signature:

But other instances don't have this problem.

• Who is affected: matrix.org
• How is this bug manifesting: Messages from iddqd.chat do not federate to matrix.org, but do federate elsewhere
• When did this first appear: ~1wk ago

Steps to reproduce

1. Send message on iddqd.chat
2. Verify that it arrives elsewhere like bolha.chat and on matrix.org
3. Notice that it arrives at the former but not the latter
