Vodafone Mobile Broadband - Getting HTTP Error 400 'An invalid request was received'

Hi,

I'm trying to connect to the website of our photographer to access photos from my wedding this Saturday just gone, I've been able to connect to it on WiFi, but when trying to get onto the site using my Vodafone Mobile Broadband it comes up with the following:

----------------------------------------------------------------------------------------------
Error 400

We're sorry, but we could not fulfill your request for / on this server.

An invalid request was received. This may be caused by a malfunctioning proxy server or browser privacy software. If you are using a proxy server, bypass the proxy server or contact your proxy server administrator.

Your technical support key is: d4b7-86d0-a52f-0448

You can use this key to fix this problem yourself.

----------------------------------------------------------------------------------------------

Clicking on 'fix this problem yourself' takes me to a page which then says:

----------------------------------------------------------------------------------------------
Technical Support

Your request was intercepted by Bad Behavior, security software which protects the Web site you visited from malicious activity, such as hackers, spam and viruses. We apologize for the inconvenience, but your request matched a profile of suspicious activity. This problem is usually quite easy to fix.

Your computer appears to have sent a request through a proxy server which corrupted the request. Uninstall the proxy server and try again. It is not normally enough to simply disable the proxy server. If you are required to use the proxy server, contact the proxy server administrator for assistance.

This problem may be caused by misconfigured or malfunctioning browser privacy software or personal firewall software. If you use this type of software, turn it off or reconfigure it and try again.

(Example: For Norton Internet Security, you need to disable the Stealth Mode Browsing feature.)

This problem may be caused by viruses or spyware on your computer, or by malicious software that pretends to be anti-virus or anti-spyware software. Ensure that you have REAL anti-virus and anti-spyware software on your computer, that they are kept up-to-date, and that you have run a full system scan using each tool. Once your system is cleaned of viruses and spyware, please try your request again.

----------------------------------------------------------------------------------------------

I never used to get this message when going to the photographer's site using my Mobile Broadband, does anyone have an idea of how to fix this problem?

Thanks...

So, basically I now can't access a website that I previously could (any probably won't be able to access more who have Bad Behavior installed) because of the way Vodafone's IP address allocation works?


PaulE_Vodafone,

Jon_Vodafone appears to know about this issue, as he answers questions on it's interference with service in the thread bacupian has linked to.

I'm not particularly happy that I now cannot access the website of my wedding photographer to be able to purchase prints of my wedding photos from home, I will have to now find free WiFi access somewhere, which obviously isn't what having mobile broadband at home was all about in the first place!

Can Vodafone not offer any solution to this problem?

Thanks,
Stu

Hi Stu,

I'm afraid there is no current solution to this problem, although we are looking at moving to public IP addressing in the long-term which will resolve these kind of issues.

Since Bad Behaviour is looking at the IP address in use, and deciding that the one you're on has been used to send Spam, you should be able to get around this problem by disconnecting and reconnecting to the internet, in order to acquire a different IP address.
You'll be able to see what your external IP currently is from websites such as www.whatismyip.org

Hi Jon,

What I've highlighted in bold doesn't work.

I've disconnected and reconnected multiple times, both before I went on my Honeymoon and as soon as I got back – to check whether the problem had been solved. I get the same message as I posted originally every time.

A long-term solution doesn't really help me, as myself and my wife have to access our photographer's website in order to select photos for our wedding book. So you can understand that I'm not particularly happy about this, since it's a problem caused by Vodafone changing their service.

Hi Stu,

Just to be clear, our service has not changed. Our network has operated this way quite happily since the 1990's - the issue here lies squarely at the feet of the developers of these blacklisting services for not only being inflexible when it comes to ISP's using shared IP addressing, but also in their overzealous nature when it comes to blocking those addresses.

Having had a closer look at the criteria Bad Behaviour uses, it looks like it'll automatically block anyone seen to be connecting from multiple IP addresses, or making multiple requests from the same IP address. Since a single public IP address on our network is shared simultaneously with thousands of other users, this is making any Vodafone user appear as if they are a "bot" and causing them to be blocked automatically, regardless of whether you disconnect or reconnect.

This is overkill in my opinion - however, reading the FAQ here, you should be able to unblock yourself using that Technical Support key you mentioned in your first post. The "fix the problem yourself" option will authenticate you as a real person, and should then allow you to browse the site normally. Can you confirm if you have followed the instructions on the photographer's site to do this, and whether it is working?

It doesn't work

he's asked you to sort out YOUR system so it works in a reasonable way. You've said Vodafone doesn't
intend doing anything about it.

Your assertion that the methods are overzealous doesn't wash with me and such responses would incline
me to up the thresholds rather than reduce them. My own low resource ftp and websites don't use
"Bad Behavior" but do block using similar criteria to those you mention, mainly vs connections per IP, and
repeat offences from an IP get added to a block list.

I've had accounts with dynamic allocated IPs since 1992, and still use such accounts, it's only since using
Vodafone's mobile broadband from earlier this year that I've come accross one sharing same IP between
different users at same time. It's been more common to find same dynamic IP being reallocated to a particular
user.

As I have already stated, we are making the move towards public IP address allocation, but this cannot take place overnight. It is not a case of us being unwilling to adress the issue, but rather that we cannot address it at this stage. We do not have enough IP addresses to provide service to all of our customers, and until RIPE, the authority that grants companies new IP ranges, approves our request, our hands are tied.

I've given information on how to make things work with our network - if you decide to do the opposite, that's obviously up to you, but it obviously isn't going to help matters.

This is because we use Private IP's rather than Public IP's, and is again due entirely to the lack of available IP ranges for our customers. RIPE will need to allocate us more before we will be able to fall in line with other ISP's.

I'm sorry to have to say you've missed the whole point.

I've never once suggested you give users there own fixed public ip, it's not even a sensible option for most
users, including myself.

What is important is that you allocate dynamic public addresses in a responsible and internet friendly way,
which if you are short on public ips to allocate should be rationed per user same as has been used without
problem on internet dialup (ie no service available try later).

As for having a choice, I'm probably moving to Orange or Three, after doing some more checking on types
of connections allowed and coverage.

I to am having exactly the same problem. I'm being blocked by Bad Behaviour from a site I've been viewing for 2 years without problem. I'm being classified as a spammer. I also get this when using Googles cache option, again my IP Address is being treated as malicious and rejected. This is getting dammed annoying...

Hi Saxonpirate,

Unfortunately, there's nothing else we can add to this at the moment, as soon as we can give you more information though we will.

I'm sorry Paul but this almost beggars belief. A company such as Vodafone is having it's customers blocked by websites because it can't sort out IP Addresses. I have this evening borrowed a "3 dongle" from a friend and accessed all the sites that are blocking me with Vodafone. If 3 can do it why can't Vodafone. I'm not one of lifes moaners, but there comes a time when you just start to feel you are being taken for a ride. If it's not one thing it's another with Vodafone Mobile "supposed" Broadband. Advertised speeds that are totally unattainable unless you live at an airport, continual dropping of connections. I could go on and on. I really regret the day I took out this 24 month contract, because for most of it my stress levels have been elevated. But even as I'm writing this I know I'm wasting my time, my money will be taken by direct debit as usual, the connection will still be as slow as a 26k modem and Vodafone will go on to make more profits. Licence to print money springs to mind!!!
