What commenters say

• The issue with SSH on macOS Catalina 10.15.4 may be due to Apple's customized version of OpenSSH.
• Using high port numbers for SSH connections is not common and may not be well-tested.
• The problem can be worked around by using the upstream version of OpenSSH and adding specific lines to startup scripts or configuration files.
• Apple's integration of key retrieval mechanisms with the rest of macOS may be causing issues with SSH connections.
• The use of high port numbers is not inherently bad design, as all purposes are equally valid on unallocated port ranges.
• The issue may have gone unnoticed at Apple because it only occurs with port numbers higher than 8192, which are not commonly used.
• The author's decision to take down the post was likely due to past negative experiences with comments on the site.
