Can't login to download.osgeo.org

[kbevers]

I seem to have lost scp/ssh access to download.osgeo.org. It last worked for me in March but now suddenly I am given a

kbevers@download.osgeo.org: Permission denied (publickey)

error.

My public key is

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC6huCQZud1biYqfsK8YreRjU8dOj5sKCJnmtTdw2O41ghHKwWo7OP5HbQ3lsXqlwVdR9jStOfx9wcWsAv6su64NXA1oJ8JYAn7TOtDx62XTXbMHrDrK3t/VFR4WL/sK9RvE9QSKxF3xRPj8tTYN+zfP0LKc5Gr8biWsngDxdVsLjm2TRqutLZGctgowGmNbFUENIeyTCgaZIjyjSCeP0UInaQD6yVmctiVWyiII/L5KDRzeZUA0p4dwoRJkpetN5RkeE8EdoGApk/jDKrMDlhyzZTkF9M8NVhXWDJiS+J8Vw/VmwXidIBLEkQuX9kg1mG0OJZgSCKJxVZJIgOwdxVr kevers@falcon.local

and my ssh config file is set up like this:

Host *.github.com
  AddKeysToAgent yes
  UseKeychain yes
  IdentityFile ~/.ssh/id_github

Host download.osgeo.org
    HostName download.osgeo.org
    User kbevers
    IdentityFile ~/.ssh/id_rsa

I get the following debug output from scp:

lost connection

I have tried removing the download.osgeo.org entry in the known_hosts but without any luck. It seems to want to use a ED25519 key instead of the RSA key that I normally use. Has some settings changed on the server that I am unaware of?
