Cannot load certain websites in 12.04

[steeldriver]

OK thanks looks like we can rule that one out then

Is it safe to say that this is not a network issue? It's just strange that only certain sites don't load and without an error message too. I'm going to try downloading another browser and see what happens.

EDIT: I tried it in rekonq and the same thing happens so it's not a browser issue.

Hello,

It might be a security issue on firewalls, networking, your provider or your router. We'll need to rule it out, first.

Go to your internet settings and make sure you are accepting cookies, java etc etc and see if you have the browser's default proxy on. If all seems well, test your security level by visiting this site;

I want to see if something else works for you, too. Next, go into your settings. Preferences -> Privacy -> Exceptions and try adding one or two of the sites you can't go to to the "exceptions" list. Confirm it, exit out and restart Firefox to see if you can visit one of the sites you added.

If that doesn't do anything, try access sites through a proxy like this one here; http://www.hidemyass.com/proxy-list/

Sadly reinstalling seemed to fix the problem for this user. But there has to be a way to fix it, so I would hold off on that for now.

Hi,

Sadly, your first link doesn't even load for me. Don't know if that says anything. I tried adding the sites to the exceptions list but that doesn't work for me either. However, when I close my settings and go back into them, they do not save and it reverts back to this setting: http://postimage.org/image/zea39oxot/.

I am able to access the sites through the proxy you posted, but of course their appearance is not very pretty.

I'm not sure if reinstalling would help or not. I tried installing ubuntu using wubi before and it gave me the same problems. This is why I wanted to try to boot from the actual .iso file on its own partition, which is what I'm running on now, but it has not made any difference.

Hello,

That is odd. Firefox is supposed to remember your settings. See if accessing the "Use custom settings for history" has all the options you checked still there. To be sure, check something not checked (or uncheck), close it and reopen to see if it is still in works. If they aren't, then not only do you have a security/permissions denial with your connection, but some problem with Firefox.

So using a proxy makes it so you can visit the sites you normally cannot? Yes, this is definitely a network form of problem. It is either how you have the network set up in Ubuntu/Distro to disallow you access, or your provider did so. But I'm going to assume it isn't the later.

Do you think you could get a screenshot of your network settings within your distro for us (But remember to block out any sensitive information like IP address etc etc!)? You could also, within Network settings, put on an automatic proxy and see if that will allow you through. Next, type in "Firewall" into your distro's search engine (Dash for Ubuntu) and set it off and see if you can access the sites without the need of the proxy.

Which network settings do you mean? Sorry, I'm still a little new to this.
This? http://postimage.org/image/3z6b57603/
Also, nothing comes up when I type in Firewall. Do I need to download an app?

No need to apologize.

Yes, I meant that. Is there other options/tabs available in the network settings? Or when you open network settings is that the only thing that appears? To the left there should be a clickable tab called "Network Proxy". Tell me what it says inside to the right after clicking into it. If it says "none", then try clicking on the dropdown box and using "automatic proxy" and see if you can load the sites. If not, switch back to the default setting it had which should be "none".

I do not remember having to install anything to edit the Firewall. Hmmm. Go to the Software Center or Synaptic Manager and see if there are any packages to download to access the Firewall.

firewall tool is gufw in synaptic package manager, its probably called something like "easy firewall" in software center.

I changed the proxy settings to automatic and asked for a configuration URL, but it had a message saying it was not needed. I tried with those settings, nothing happened.

I installed something called Firewall Configuration and it gives me this:

It was already set to 'off' when I opened it.

Hello,

It will need a configuration URL for it to work. Does it give you a place to get the URL, or? As for the Firewall, try setting it to "on" and "allowing" all of it through.

And thanks for the name of the firewall download, black veils. I couldn't remember what it was called.
