403 error updating let's encrypt certificate

[tm1000 (Andrew Nagy)]

Solution:

Trouble updating Let's Encrypt Certificate with non default ports

Try Sysadmin 13.0.71.2, which is currently in ‘Edge’ mode - you can download it manually by switching your machine to egde, or just run ‘fwconsole --edge ma upgrade sysadmin’, which will get the new Sysadmin package. Then all you need to do is go into Port management and click ‘Save’, which will generate a fixed httpd.conf!
