the update to TrueNAS Core 13-U4 went smoothly. But since the 13-U4 I can’t update a jail from 13-p5 to 13-p7 via the GUI, because I get the error message entered in the header.
At my Internet Firewall i have entered the update FQDNs as an exception, so that a MiM is not used with the FQDNs. I currently lack the idea why the error message comes up (even with completely newly created jails).
Does anyone have an idea what to do to fix the error ?
