We are trying to use the Git Backup extension 2.0.2 on ThingWorx 8.4.1 with GitLab community edition hosted on-premises. When trying to push to the repository this fails with an error message (server FQDN has been modified):
Push Error: org.eclipse.jgit.api.errors.TransportException: https://enterhostname.customer.local/iot/thingworx-test.git: Secure connection to

The SSL-certificate of the GitLab-webserver is trusted by Google Chrome when I try to access GitLab from the ThingWorx server.
There seems to be something else that has to be configured to make this working. We are using a self-signed certificate in .local domain.
Any help is appreciated. Thank you.
