View Full Version : Problems accessing website
I've got two little problems:
1) One of my staff is having trouble accessing my website for a couple of days now yet everyone else can see it. I'm using PHP-Nuke with a built-in security script called Sentinal, but that hasn't blocked him (just checked). His ISP is NTLworld, based in England. My website is www.uozone.com . He can't access other sites on cluster's 9 (the one I'm on) either, but he can see powweb.com.
2) I have a subdomain wonuo.uozone.net and a domain www.wonuo.net. The nameservers for the latter domain is set to ns3 and ns2.powweb.com. My .htaccess in the main domain directory is set as below:
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !^/+me/
RewriteCond %{HTTP_HOST} ^(www\.)?meuo\.net$ [NC]
RewriteRule ^(.*)$ ./me/$1
RewriteCond %{REQUEST_URI} !^/+wonuo/
RewriteCond %{HTTP_HOST} ^(www\.)?wonuo\.com$ [NC]
RewriteRule ^(.*)$ ./wonuo/$1
... yet nothing happens when I type www.wonuo.com. Strangely, it used to work about a week ago, now it doesn't.
Any ideas what could be wrong?
Thanks.

Did you define the wonuo.net and wonuo.com domains as pointer domains is OPS > package > overview (at the bottom) ?
Oh Doh! I forgot to add it there. Alright, that solves problem #2, any ideas for #1?
What error does this user see? Please provide as much detail as you can.

There is more to the error than that. What is the actual error as listed at the bottom of the error page?
Alright, I thought it looked like a general error. Here is the whole page.

Ok, now we're getting somewhere. The user's system can't resolve your hostname. There are many possible reasons for this, including misconfiguration by the ISP. Assuming this is a Windows system (probably a good bet), have them do this:
Start..Run. Enter "cmd" without the quotes and click ok.
At the prompt, type:
nslookup www.wonuo.com > c:\lookup.txt
and have them send you the contents of c:\lookup.txt. Post it here.

nslookup www.wonuo.com > c:\lookup.txt
News from Sweden:
That domain can't be resolved from here.
nslookup www.wonuo.com
Server: dns1.swip.net
Address: 130.244.127.161
*** dns1.swip.net can't find www.wonuo.com: Server failed
Remove unwanted ./ from rules, as well.
And add [L] flag
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !^/+me/
RewriteCond %{HTTP_HOST} ^(www\.)?meuo\.net$ [NC]
RewriteRule ^(.*)$ me/$1 [L]
RewriteCond %{REQUEST_URI} !^/+wonuo/
RewriteCond %{HTTP_HOST} ^(www\.)?wonuo\.com$ [NC]
RewriteRule ^(.*)$ wonuo/$1
The problem with the wonuo.com domain was because I didn't add it to the package info, but that's solved now. However he is still having problems with accessing my main website, www.uozone.net. This is what lookup.txt gave:
Server: cache1.ntli.net
Address: 194.168.4.100
Name: uozone.net
Address: 66.152.98.209
Aliases: www.uozone.net
EDIT:
I added extras htaccess. wonuo.com still has to resolve in the powweb packages.
Ok, what is the full error he gets for uozone.net?
The error I posted above is the one for uozone.net

That is the full error. as Crius posted before.
Well, if the nslookup output is correct, then there's something else wrong somewhere between you and PowWeb. What happens if you try to access http://uozone.net/ ?
I just said what happens. if you read my last post i pasted it, i have tryed with www. and without it
He's getting the same problems with these urls:
www.theDFWscene.com
www.LowIncCustoms.com
Which are also on cluster 09.
Ok, can he access http://clust09.powweb.com/ ?
And Paul, I assumed that the error was for the hostname with the www - I wanted you to try it without.
No he can't, he gets the same error as before. Same error for the http://clust09.powweb.com , for the http://uozone.net and http://www.uozone.net url's.
Ok. Back to the command prompt, and this time type in:
tracert clust09.powweb.com > c:\trace.txt
and post the contents of trace.txt

No he can't, he gets the same error as before. Same error for the http://clust09.powweb.com , for the http://uozone.net and http://www.uozone.net url's.
Did your friend contact his ISP and ask if the IP of cluster09 may be blocked for whatever reason ?
It has happened before that an ISP was ordered to block a server cause of illegal activities by a website hosted there (was a Spamish issue at the time), and all other sites on the server were hit by this action too.

Hi, at this point I'd better join in.
I have a website www.thegoalposts.com on cluster07. I have never had a problem with it until Friday, on returning home from work to my NTLworld account there suddenly wouldn't let me access my site. I went to my parents house and could not access from there either ...they are also on NTLworld. However I went to work and could access the site, no problem.
I have messed about with my settings, my cache, my browser... checked my ftp up and down and could find no wrongdoing at all by myself. So I was almost relieved to read this thread is it points the problem straight at the ISP, NTLworld.
I have tried the other sites listed on the thread and all the evidence points to a block by NTL or Powweb.
I would think there are a vast number of NTLworld users affected by the change and may suddenly find themselves blocked from powweb sites.
I have been able to access my site via the secure powweb address but I am locked out of admin and have only been able to run my site effectively this weekend via my co-admin. This is not exactly a desirable situation, as you can imagine. :(
Anything powweb staff can do to help at this point would be greatly appreciated.
I recommend you contact PowWeb support and give the IP address of your system. I know in the past there have been issues where PW had blocked particular IPs or IP ranges in their firewalls as defense against a DOS attack and left the blocks in place. If you later get assigned the same IP, you could have a problem.
That the tracert completes is rather curious - that suggests a specific port block.
I thought that might be the reccommendation... :(
I have contacted support and given them as much detail as possible. I agree that this is highly likely to be a block at the powweb end as the reverse would mean the unlikely blocking of several domains at the NTL end, whereas powweb only need to block one IP.
NTLworld is notorious for using a single shared static IP address for regional cable broadband users and I think this is likely to be a case of block one / block 'em all.
Although I sympathise with the need to block problem IP's, for me (and it seems others) it has been a lost three days. :(
Least im not the only one :)
