Can't access websites, "URL not found on server"?

Alain,

I did have the hosts file edited and inserted the # sign at the beginning of each line but no luck.

However, one difference is that my browsers (Safari, Chrome, and Firefox) are all giving a 404 error but on the SSL site (https) so that it's port 443 that's being accessed. My Net scan of www.adobe.com results in both 80 and 443 open ...

I think that it's due to a hosed setup of Lion Server ... wish I never installed the **** thing. I've turned off everything in Server.app and restarted but still no luck.

Also, my local and WAN file sharing is not working to this computer.

Any ideas ?

It was the hosts file after all. Nano didn't accept my changes but I didn't notice ...

Hi There,

I am reading through this post and trying miscilaneous things and still have the same problem. I cannot access Adobe.com. I am on OsX 10.7.4. I have a laptop on the same system that can open the website fine- they are also both on the same wifi network. I just can't open it on my desktop. I hope someone can help- I am desparate! Thanks in advance.

Insert the following into Go to Folder:

/etc

Open the file hosts with TextEdit and ensure that it contains minimal information such as the following and nothing else:

##

# Host Database

#

# localhost is used to configure the loopback interface

# when the system is booting. Do not change this entry.

##

127.0.0.1 localhost

255.255.255.255 broadcasthost

::1 localhost

fe80::1%lo0 localhost

Hi Neville- thanks for helping!

I feel really dumb, but not sure what you mean by "Go to Folder"? Is this on my Mac or Safari? Sorry I am a little lost can you claify on that part.

Thanks!

Neville (next post) is right. But you can do a quick terminal command to see what the hosts file looks like now.

From Terminal type : cat /etc/hosts

This will list the hosts file (as in Neville's post) to the Terminal window. It should contain some Adobe addresses rerouted to 127.0.0.1 - if not your problem is something else. If yes, then follow Neville's instructions.

So I followed your instructions and found the following- what next? :

##

# Host Database

#

# localhost is used to configure the loopback interface

# when the system is booting. Do not change this entry.

1. Go To Folder is a menu item from Finder under the Go menu. It's a way to get to the where the hosts file is.

2. To get to Terminal look in Applications then in Utilities.

3. To edit the file (hosts), first find the file in the list then RIGHT CLICK and select Open With ... then select TextEdit from the list.

4. Remove the lines that look like this (if they are there and this is indeed your problem) :

127.0.0.1 3dns-1.adobe.com

5. Save the file and try to access the site(s) again

Hope that helps.

Ed

Oh, remove ALL the adobe.com lines and leave everything else !

Hi Ed,

When I try to edit the host file, it says locked and I get this message..

You don’t own the file “hosts” and don’t have permission to write to it.

So I unlocked the file, and went back and tried again and got the same message. It seems to lock right after I unlock it.

So then I made a duplicate, but it wouldn't let me replace it. Any suggestions?

Thanks!

If this hels at all there are a few host files, not sure if this means anything. But here is a screenshot...

The only one which concerns your problem is the one named 'hosts' (which is located in /etc/ folder)

And you must have the administration rights on your mac to be able to modify it., Then once the file is edited, as Neville said, you should only keep in it the following content:

##

# Host Database

#

# localhost is used to configure the loopback interface

# when the system is booting. Do not change this entry.

##

127.0.0.1 localhost

255.255.255.255 broadcasthost

::1 localhost

fe80::1%lo0 localhost

I'm wondering if someone knows a command line to overwrite the content of the /etc/hosts file by the content of another file.

Maybe to ease the modification for picklesmau, can we imagine creating a .txt file somewhere filled with:

##

# Host Database

#

# localhost is used to configure the loopback interface

# when the system is booting. Do not change this entry.

##

127.0.0.1 localhost

255.255.255.255 broadcasthost

::1 localhost

fe80::1%lo0 localhost

then using the Terminal, launch the cmd line to copy/replace all lines from the txt file into the /etc/hosts file ?

I actually do have the administrative rights to modify thats why I am so confused.

Alain if you give me the step by step for the above suggestion- I will give it a go. The unlocking - locking situation is still the same on the host file.
