I have the same issue appears to be in KeyVaultOperation.fillSecretsList()
Java 11.0.5+10
azure-spring-boot: 2.2.3
Spring Framework: 5.2.4.RELEASE
Spring Boot: 2.2.5
Reactor: Dysprosium-SR6

    private void fillSecretsList() {
        try {
            this.rwLock.writeLock().lock();
            if (this.secretKeys == null || secretKeys.size() == 0) {
                this.propertyNames.clear();

                final PagedIterable<SecretProperties> secretProperties = keyVaultClient.listPropertiesOfSecrets();

               //Hangs here:
                secretProperties.forEach(s -> {
                    final String secretName = s.getName().replace(vaultUri + "/secrets/", "");
                    addSecretIfNotExist(secretName);
                });

                this.lastUpdateTime.set(System.currentTimeMillis());
            } else {
                for (final String secretKey : secretKeys) {
                    addSecretIfNotExist(secretKey);
                }
            }
            propertyNamesArr = propertyNames.toArray(new String[0]);
        } finally {
            this.rwLock.writeLock().unlock();
        }
    }
