As I was following through the tutorial (https://www.digitalocean.com/community/tutorials/how-to-encrypt-tomcat-8-connections-with-apache-or-nginx-on-ubuntu-16-04), even though it has been on Ubuntu 20.04 and Tomcat 9, it did not work.
When finally restart apache2, connection to my SSL secured domain is not working and in /var/log/apache2/mod-jk.log I got the error:
[Wed Mar 24 12:44:32.794 2021] [9160:140230644751424] [error] extension_fix::jk_uri_worker_map.c (580): Could not find worker with name ‘ajp13_worker’ in uri map post processing.
Any help would be greatly appreciated.
