ProcessMaker is configured to respect the structure: xxx/sysworkflow/en/classic/login/login, so changing it to:
http://XXX.XXX.XXX.XXX/processmaker/
it won't work unlike wordpress that you have the possibility to create subfolders.
In the case of ProcessMaker domains or ports are created to have access. In your case you can create a rule to redirect your URL to processmaker login, it means when you enter to
XXX.XXX.XXX.XXX/processmaker/
it redirects to:
xxx/sysworkflow/en/classic/login/login
You need to modify your .htaccess
file or pmos.conf
file depending on how you installed ProcessMaker.
This information may help you to redirect your URL.
Regards.
