Last Updated on January 5, 2022 EST by Jordan

If you’ve been using the MSP360 backup client on older CentOS hosts, you might have run into this error.

SSL certificate problem: certificate has expired

Upon further investigation, the agent error log /opt/local/Online Backup/<INSERTUUIDHERE>/logs/log_worker_<ANOTHERUUID>}.log show the following errors.

The issue was being on the client version Linux (rpm) v. 3.2.0.114 of which this MSP360 community support thread speaks about upgrading to the latest version of the client.

To do so, you need to click on “Downloads” from your MSP360 admin dashboard and request the update of the default build. The new build ended up being 3.2.3.156

Once done, you can then update your clients under RMM->Remote Management, then click the settings icon to the far right and then click “Force Update”.
