I am currently unable to connect to sites using http, but can connect via https. I can get to microsoft.com on https, but not http. I am using IE7 (and Firefox) on XP Pro SP2.

I am sure it is going to be a simple setting somewhere but I cannot for the life of me find it.

I've had a look at those suggestions but my problem is the exact reverse. I can only access secure sites (and FTP).

For the record, I have turned off the windows firewall (I'm behind an ADSL router with NAT) and still cannot access normal non-secure sites.

my apologies..I wasn't reading properly..

are you using IE? If so, what have you got for the privacy and security options?

I'm using IE7 and FF 1.5. Neither works. I have "RESET" all IE settings to defaults, to no avail.

What happens when you try and access a normal http site? Error message?
It sounds like something is blocking port 80.
I take it your email still works?

I get a page that says :

Internet Explorer cannot display the webpage.

Most likely causes:
- You are not connected to the Internet.
- The website is encountering problems.
- There might be a typing error in the address.

What you can try:
- Diagnose Connection Problems
- More Information

Selecting Diagnose Connection Problems and following the instructions produces a diagnostic log as follows:


info: FTP (Passive): Successfully connected to ftp.microsoft.com.
info: HTTPS: Successfully connected to www.microsoft.com.
warn: HTTP: Error 12029 connecting to www.hotmail.com: A connection with the server could not be established.
warn: HTTP: Error 12002 connecting to www.microsoft.com: The operation timed out.
error: Could not make an HTTP connection.

Another quick test just to confirm that it is port 80 that is not working:

Try and go here (http://diwana.org).
You should get the error you have been getting.

Now try here (http://diwana.org:81)
You should hopefully get the diwana.org website.

Might be a firewall stopping it, what firewall is installed.

Disable it and see what happens.

CYaBro, tried both those pages with no luck.

Speedy, no firewall. Was using only Windows Firewall on this machine (a laptop) but have completely disabled it for the moment.

I'm still trying different things and will update as I get results.

Have you powered off and on your ADSL router?

Yes.

Latest update - I restarted the computer and was able to access web pages. Diagnostics showed FTP, HTTPS and HTTP were all working. I fired up Ad-Aware and downloaded the latest files. The computer is also running CA eTrust Integrated Threat Management (AV and Pest Patrol) so I got that updated to the latest definitions. After about 4 minutes it all died again - diagnostics now show FTP and HTTPS working, but a problem with HTTP.

I will run full Ad-Aware scan and AV scan and update this thread.

Not sure if it's relevant, but there are no LAN problems. I can map drives on other computers on my network.

Have been doing some more investigation and have discovered the following:

After a restart I can access web pages for between 4 and 5 minutes. After this period I can only access FTP/HTTPS.

If I access a streaming video, it will continue streaming.

The inference is that port 80 is open for only a few minutes before something blocks it. Is there anything I can use to view the status of the ports on my computer?

I would surmise that one of the apps installed is blocking port 80 and this happens after the program has started hence the 4-5 min when it works.

So, I would STOP the programs one by one until it works.

Maybe the ad-ware has disabled something when its done a fix!

Yeah a look-see in his msconfig startup file might be helpful.

Hi I have the exact same problem here (only have to access to https, not http):

HTTP, HTTPS, FTP Diagnostic
HTTP, HTTPS, FTP connectivity

info FTP (Passive): Successfully connected to ftp.microsoft.com.
info HTTPS: Successfully connected to www.microsoft.com.
warn HTTP: Error 12029 connecting to www.microsoft.com: A connection with the server could not be established
warn HTTP: Error 12029 connecting to www.hotmail.com: A connection with the server could not be established
error Could not make an HTTP connection.

Your suggestions and solutions will be highly appreciated. Urgent!!! Have a happy thanksgiving!!

Hi Jack,

I'd love to be able to say "do this" or "do that" and it will be fine, but I never did get to the bottom of it. I tried several things :

1. Ran System File Checker sfc /scannow which made no difference.

2. Tried to do an XP Repair. Got XP disks and registration codes mixed up, so restarted half way through and that was it - end of machine - would not boot.

3. Only remaining option - reloaded machine from scratch using recovery discs.

So far the problem has not recurred.

Sorry I can't be any more help.

I had the EXACT same problem as Miami Steve and wanted to post this here to make sure someone else saw this.

The fix appears to be making sure that your firewall is turned ON for your VPN stack. At least, that appears to fix the issue for me.

This is an odd issue, because I was able to use HTTPS and FTP, AND I could use HTTP as long as it wasn't over the standard port 80. I suspected my VPN client for some time, so I was poking through it's menus where I saw a 'Stateful Firewall (Always On)' option in the menu; in Advanced Mode for our client. I clicked this, which put a checkmark next to it in the menu, and then tried my regular HTTP sites again and it worked! :cool:

I have several poorly developed theories on why this might be the case, but I guess the point of this post is that if you have a VPN client installed, then toggle its firewall setting on <=> off to see if this fixes your problem.

Just a thought - seen one problem like this before ages ago - go into your internet options settings in the control panel, Connection Tab, Lan Settings and make sure "use Proxy server" is UNTICKED.

This worked! I've been trying to fix this forever and your suggestion worked. Please believe me when I say I will love you forever!

Thanks so much.
