In some scenarios, when domain names can resolve to multiple IP addresses Foglight can experience connectivity problems when reaching external services such as LDAP or SMTP; connections can only be restored after the Foglight service is restarted. Examples:
Active Directory (AD) user cannot login; authentication failures due to LDAP server connection timing out:
YYYY-MM-DD hh:mm:ss.SSS WARN [http-exec-5] com.quest.nitro.service.security.util.LdapSearcher - Error connecting to LDAP server: ldap://ldaphost:389/
javax.naming.CommunicationException: ldaphost:389 [Root exception is java.net.ConnectException: Connection timed out: connect]
...
YYYY-MM-DD hh:mm:ss.SSS ERROR [http-exec-10] com.quest.nitro.service.security.auth.spi.NitroExtendedLdapLoginModule - Error pre-binding to LDAP server. Check the LDAP configuration (Probably the service account password expired).
SMTP server not reachable when sending email notifications or testing the mail configuration:
YYYY-MM-DD hh:mm:ss.SSS ERROR [Action-5-thread-37] com.quest.fod.email.extension.EmailExtensionAction - EmailExtensionAction.exception when execution EmailExtension action: []
org.springframework.mail.MailSendException: Mail server connection failed; nested exception is com.sun.mail.util.MailConnectException: Couldn't connect to host, port: hostname, 2587; timeout 180000;
nested exception is:
java.net.ConnectException: Connection timed out: connect. Failed messages: com.sun.mail.util.MailConnectException: Couldn't connect to host, port: hostname, 2587; timeout 180000;
Subscription license cannot be updated when unable to reach QorePortal after the IP address changes:
YYYY-MM-DD hh:mm:ss.SSS INFO [pool-3-thread-1] com.quest.nitro.service.licensing.LicensingService - Subscription licenses update:
: License update failed - Fail to retrieve license from portal: Connect to msp-api.licenseportal.com:8093 [msp-api.licenseportal.com/52.224.68.104] failed: Connection timed out: connect, expiry is YYYY/MM/DD
