    My ISP has been no help, my server provider has been no help, so I'm turning to all of the greatly helpful people in here.

    I have a handful of domains hosted on my WHM/cPanel server (leased through Rackshack) that randomly go between being accessible and not being accesible when using ANY prefix before the domain name..

    Example:

    SOMETIMES I can access the website http://www.wallycook.com
    SOMETIMES I CANNOT access the websites http://www.wallycook.com

    Whenever I CANNOT access http://www.wallycook.com, I CAN access http://wallycook.com

    For mail servers, SOMETIMES I can connect to mail.wallycook.com
    But SOMETIMES I have to use just wallycook.com as the mail server because I can't connect to mail.wallycook.com

    As I write this message, I cannot access http://www.wallycook.com or http://www.thepaulleys.com, but I CAN access them if I leave the www. off.

    I am at a loss because I don't understand why SOMETIMES it works and SOMETIMES it doesn't -- there is no pattern, no error messages in the server logs, nothing... it just stops being accessible.

    This was happening a lot with one of my larget clients ($200/mo account) and they cancelled with me and move to another provider because of this problem... I really need someone to help me track down the reason this is going on and help me develop a permanent fix.

    Thanks!

    Well it's doing it again, and one of my $80/month clients just quit!

    DOES ANYONE KNOW A 100% WAY TO FIX THIS!??

    Have you checked the httpd.conf file to make sure the
    ServerAlias www.domain.com domain.com
    line is still there when you have trouble?

    It may not be the problem, but it's the first place I would check.

    The next place I would check is the file in /var/named to make sure these 2 lines are still there.
    mail 14400 IN CNAME domain.com.
    www 14400 IN CNAME domain.com.

    Also, are those domains running on DNS on separate machines? Check that all DNS machines have the correct DNS zone files. Perhaps they aren't synching?

    That could be a DNS problem.

    I go to dnsreport.com and check for that domain you give me, and the ns2 fails...

    Check you nameservers.

    I have that problem too, and the error was on nameservers bad configured.

    Hello,

    I have this exact same problem as mentioned in the first post. My httpd.conf file is fine as well as the named file. I have also had my DNS configuration checked on my server by two reputable people who have said it looks just fine.

    Why this happens where the www works and than other times not, I have no idea. It really is a lot of trouble sometimes.

    My server is also at RS too.

    Oh well, I guess this is one of those research problems where it just takes time to figure out.

    There is definitely an issue here however, as I have scoured the net and have found many posts like the one above. The solution is quite an elusive one for sure.

    Oh well, we'll see if one pops up in the future sometime.

    Thanks

    Hi there,

    I am still not exactly sure how to solve the problem, but here are a few things that I did which seemed to take care of it.

    1. I checked dnsreport.com and attempted to fix other areas that were either in red or yellow. Most importantly I assigned reverse DNS records to everything. Plus there were a few other areas that I researched and checked.

    2. I usually do an upgrade of cpanel, and restart some services such as bind and apache.

    3. I check the usual areas such as httpd.conf, resolv.conf, and named to verify the domains are set up properly.

    4. I check again, my dns zones in WHM to either verify or even sometimes re-enter the same data in case it didn't catch the first time.

    This can sometimes take some time over the course of a day, but almost always after I do this the problem goes away. Again, exactly which thing corrects the problem, I have no idea.

    So, I guess so far "Time" is the only thing that seems to fix it.

    :rolleyes:
