Problem after upgrading to 3.1.15p3
Upgraded yesterday and now 3 of the 7 domains I host are having issues with SSL. All worked fine until the upgrade, SSL and Lets Encrypt are checked and valid certificates exist according to ssllabs.
Each of the affected domains host a "website" that forwards to another domain on the server that shows up as secured - so it is tricky to see the problem.
The issue is that the domains where SSL is not working hosts our email server and needs a secure connection.
Any idea of how to fix this.
Thanks for your help
