For SFTP Gateway version
3.2.1, there is a critical issue where Java will no longer start. This is due to a license expiration in one of our software dependencies.
To resolve this issue, you will need to perform an in-place upgrade to version
How to find out if you have this issue
You may encounter an issue where the SFTP service stops working, and the web admin portal waits indefinitely for the backend Java service to come up:
Please wait while SFTP Gateway finishes setting up and try again in a minute... Meanwhile, take a moment to view our documentation for setting up SFTP Gateway version 3.2.1.
This happens after a recent reboot, or a restart of the Java service.
When you check the application log, you will see these error messages:
Caused by: com.sshtools.synergy.nio.LicenseException: Your support and maintenance has expired! You should either downgrade to a version your license supports, or purchase a new maintenance package. at com.sshtools.synergy.nio.SshEngine.startup(SshEngine.java:201) at com.sshtools.synergy.nio.SshEngine.startup(SshEngine.java:180) at com.sshtools.server.AbstractSshServer.start(AbstractSshServer.java:136) org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'embeddedSftpServer': Invocation of init method failed; nested exception is java.lang.IllegalStateException: com.sshtools.synergy.nio.LicenseException: Your support and maintenance has expired! You should either downgrade to a version your license supports, or purchase a new maintenance package.
When restarting the Java service (
service sftpgw-admin-api restart), Java fails to start.
Note: This bug only applies to SFTP Gateway version
Upgrade to version 3.3.2
The current solution is to perform an in-place upgrade to version
You won't be able to perform an upgrade using our migration article, because you won't be able to export your users and settings when the web admin portal is down.
