Regarding the settings of Secure Connection

I set the content of conf, but when I connect to www.i-cna.com/gps, I only see Traccar in the name of the web page, but the content of the web page is blank.

Have you done this part?

Note that you also need to recompile the modern app for it to work correctly on a new path.

How do I recompile the moder? Is there any relevant document I can refer to? Didn’t I modify the settings of Pweb server?

You probably haven't installed dependencies. I also suspect that you haven't actually changed any of the code.

I just want to change http://ip:8082 to https://www.i-cna.com/gps. This seems to only require changing the configuration of the WEB SERVER. I changed the configuration, but it did not take effect.

I already told you it's not correct. You have to change and recompile the web app.
