Need clientCert as temporary solution

Help
1

I'm trying to get a temporary Client Authentication Certificate, but my account is not allowed to request the tlsclient profile.
Could my account (3358957766) be added to the allowlist for this profile?

error creating new order. Le_OrderFinalize not found. {
  "type": "urn:ietf:params:acme:error:unauthorized",
  "detail": "Error creating new order :: account ID 3358957766 is not permitted to use certificate profile \"tlsclient\"",
  "status": 403
}

There is no manual allow list for the tlsclient profile as far as I know. If you were using the profile before 2026-05-13, you can still use it (account automatically on the allow list), but it appears you did not. Or at least not with that specific account.

Please see Ending TLS Client Authentication Certificate Support in 2026 - Let's Encrypt for more information.
