Apache not working offline

Hi everyone.
I'm having a strange problem with Apache. I use it for local development and I don't understand why, if I disconnect from the internet, I can no longer see my local websites.

When the computer is connected to the Internet, the local server also works perfectly.

Thank you all.

Re: Apache not working offline

Check the logs, they will show what the problem is, usually anyway

 cat /var/log/httpd/
access_log  error_log

Re: Apache not working offline

I went offline to reproduce the conditions where the local server is down and deleted the two files before restarting the local server.

Re: Apache not working offline

If you access the root http://localhost you should get something in the access log.

Re: Apache not working offline

Okay. I don't understand what happened, but everything seems fine for now. When the problem arises again, I'll try to add more details.
Thank you SimonJ. Thanks everyone.

Re: Apache not working offline

Now I understand what it depends on. I should have thought about it before.

I'm trying Tomoyo, and for a while I had swapped profile 1 of domain /usr/bin/httpd with profile 3. Then I put profile 1 back, and everything seemed to work. I didn't think about it again until this strange behavior appeared: everything works when my laptop in connected, but offline I can't access my local websites.
I tried the swap again, and it did it again, so it definitely depends on my policies. Something must have remained. When I'm offline, httpd doesn't work at all: it doesn't even write anything to the logs. When I'm online, everything works. I think it's really weird.

Anyway, there's no real problem: I do it all just because I enjoy learning something. Maybe I'll get there eventually, or maybe it'll seem too complicated and I'll give up.

For now, the problem is that I haven't understood why this odd behaviour disappeared at a certain point. Any ideas?
