 **Remark 2:** Orthanc SCU and Orthanc SCP share the same set of
 trusted certificates.
 
+**Important:** `DCMTK 3.6.4 seems to have an issue with DICOM TLS
+<https://forum.dcmtk.org/viewtopic.php?t=5073>`__, which produces the
+errors ``DUL secure transport layer: no suitable signature algorithm``
+(in the DICOM SCP) and ``DUL secure transport layer: sslv3 alert
+handshake failure`` (in the DICOM SCU). Make sure to use either DCMTK
+3.6.2 or DCMTK 3.6.6. In particular, Debian Buster (10) will use DCMTK
+3.6.4 and should be avoided in non-static builds of Orthanc, or if
+using the DCMTK command-line tools.
