Hi!, well, if you do not have job, TLS will not works. You should try to script TLS configuration, pressing bottom 'Script Configuration', and create the job re-executing this backuped configuration. In deed, this is a good practice, so if you need to reconfiguring TLS, just uncheck 'Enable this a primary database in a log shipping configuration' option to delete previously created jobs, and by execution of this scripts, will be on road again.

I hope this help you.
