+--------------------------------------------------------------------------------
 Failed to register with the ACME provider. This is likely happening because the install
 is new, and ACME v1 has been deprecated by Let's Encrypt and is disabled for installs set
 up after November 2019.
 At the moment, Synapse doesn't support ACME v2. For more info and alternative solution,
 check out https://github.com/matrix-org/synapse/blob/master/docs/ACME.md#deprecation-of-acme-v1
