The log entry:
ERROR [net.shibboleth.idp.plugin.authn.duo.impl.HealthCheckDuoOIDCAuthAPI:97] - Profile Action HealthCheckDuoOIDCAuthAPI: Duo API health check failed
net.shibboleth.idp.plugin.authn.duo.DuoClientException: Could not execute Duo HTTP request
        at net.shibboleth.idp.plugin.authn.duo.nimbus.impl.NimbusClient.executeRequest(
Caused by: none: Name or service not known
        at java.base/ Method)

I've duplicated everything in to add the new "secureduo" (I didn't like "special")... without success. By changing the entity in duo-oidc-authn.xml I can send to the second instance successfully...

I guess that would depend on the error but there isn't much else to assume but that your integration settings for that one are wrong. Using properties for this gets very ugly very fast and is extremely error prone.
