VM proxy & Google problem
 

Hi all,

I always have to use webcache.virginmedia.com to browse as without it, browsing has always been impossible for me. Today however, using the proxy, Google gives me the below error and entering the captcha characters it suggests simply returns a blank page.

If I disable the proxy, Google works fine but websites clicked from the results and any others elsewhere, time out (as they always do).

Anyone have any ideas? I've done a scan etc and nothing untoward is happening. Can anyone replicate it using the proxy?

Re: VM proxy & Google problem
 

Looks like they've blacklisted the address of the VM proxy. You could try contacting google, explaining to them that it's a proxy address, and them registering multiple requests from the proxy's address is normal.

or.....

Work out why you need to go for a proxy for everything.

Re: VM proxy & Google problem
 

It's likely that all requests to Google through the webcache come from the same IP address - so it's Google anti-flooding/spam/virus protection kicking in

Re: VM proxy & Google problem
 

OK, there is possibly a serious underlying problem if you HAVE to use a web cache to browse the web all the time.

I know that's kind of a "DUH" statement to make, but that would really concern me. What kind of network set up have you got?

Re: VM proxy & Google problem
 

Thanks all. Some Googling (ironic..) suggests that it's a spam flood reaction from Google. Phew.

Yeah, I have been thinking it's something I need to look at (why I have to use the proxy) but I seldom have time to sort it out. I usually need to access sites and services very quickly to get stuff done and well, the proxy allows that.

I'm using up to date Firefox. PC is hard wired to a Netgear wireless router. IE has the same problems, if not worse. I've had browsing problems with VM ever since I went from STB to CM, and I've been through a few PC's since then and not always using a router.

Re: VM proxy & Google problem
 

can you runa tracert to some sites liek google, bbc as this sounds liek routing issue as hte proxy will rotuer oyu another way to it without it

Re: VM proxy & Google problem
 

Dunno if it makes any difference but these are taking ages to complete.

1st tracert to theplanet.com says: Unable to resolve target system name theplanet.com.
2nd works but :

Re: VM proxy & Google problem
 

Sounds like it may be a dns issue, what dns servers are you using ?

Re: VM proxy & Google problem
 

The router & NIC are currently set to auto from ISP, Paul. I have noticed improvements with others in the past but prove to be sporadic so have been sticking with VM's.

:Edit:
Actually changing the DNS servers on the router to OpenDNS and then flipping back to the webcache proxy in the browser gets me all up and running again on Google so thanks for the reminder.
It'd be nice one day to have everything VM default and hunky-dory. I often wonder how someone with lesser 'messing with settings' knowledge would cope with a scenario like this.

Re: VM proxy & Google problem
 

point 2-5 also seem a bit high so there could be a problem our side did ypu do that with webcache off?

Re: VM proxy & Google problem
 

Yeah, webcache off Andrew.
I'm using OpenDNS now and Google is working but I'm still experiencing intermittent website stuttering so I'm not home & dry just yet.

Re: VM proxy & Google problem
 

It maybe worth checking your MTU settings. Have you tried running any TCP optimising software?

Re: VM proxy & Google problem
 

Nope. Used to be a big fan of Dr TCP in the XP days. Since Win7 though I thought we were all good.
rwin?

Re: VM proxy & Google problem
 

I think receive window size can also have some detrimental effect too

Yeah didnt realise you were on win 7
There is a version of TCP optimiser for win 7 although I always thought Win 7 was meant to optimise itself

Re: VM proxy & Google problem
 

Yeah, thanks.
See, with the webcache on I (usually) have zero problems. Quite the opposite - everything loads in a flash, so I'm loathed to mess about with Win7's default on that tbh.

all I was wandering was Win7 preinstalled or have you upgraded. Wandered if a registry setting had not been changed successfully if an upgrade

Re: VM proxy & Google problem
 

Clean install mate.

Re: VM proxy & Google problem
 

Tis bizarre that you have to go through proxy. I assume all your modem signal levels are correct, although I would have though that would've affected proxy too. 192.168.100.1 user = root password = root

Re: VM proxy & Google problem
 

Speedguide suggests an rwin change I notice.. I may have a go.

Presume this is what you'd need to look at?

Re: VM proxy & Google problem
 

Yes and that is all good (as far as my knowledge goes)

Re: VM proxy & Google problem
 

Yeah, I guessed as much. Usenet maxes out and I have no http download problems - it's just browsing.

Re: VM proxy & Google problem
 

crazy

Re: VM proxy & Google problem
 

FWIW, everything is super-fast again now using OpenDNS and no proxy. :confused:

With inconsistent page loads like this it's hard to pin it down to one thing I guess.
Thanks for all the help though. I think I'd get bored if it was all plain sailing.
;)

Re: VM proxy & Google problem
 

I personally use Google's DNS 8.8.8.8 and 8.8.4.4

glad it is all working

Re: VM proxy & Google problem
 

Interesting. They (Google's) failed to provide decent results for me in the past but are working ridiculously well now. Thanks again.

Re: VM proxy & Google problem
 

No problem
