Resolved SSL cert for Mail not renewing itself

[SigmundS]

Hello there,
I have a slightly annoying problem. I am securing my Plesk login and Mail with Let`s Encrypt. The renewal of the certificates with LE works, but plesk does not update them. I have to login to plesk, go to
Tools & Settings -> SSL/TLS Certificates -> certificate for securing mail "Lets Encrypt mydomain.com from mydomain.com". [Change]
Then I hit the change button and hit ok (the correct cert is allready set).
Why is Plesk not using the correct cert?

Thx 4 F1.

s.h.

System: Root Server with Ubuntu 14.04.5 LTS‬ and Plesk Onyx Version 17.0.17 Update #38

As far as I remember it was fixed in Plesk Onyx 17.5
Consider upgrade possibility.
