Getting 403 Forbidden Errors Some times
Hello,I have a VPS .
Server Load 0.57 (4 cpus)
Memory Used 59.8 %
Swap Used 23.93 %
Disk vzfs (/) 50 %
my server is up and i dont use all of memory but there are a lot of 403 forbidden errors when i refresh the page 3-4 tmes it opens do you know where is the mistake

they are most of times ok but some times giving these errors for example when it gives in
http://www.exampleclient.com 403 error
i type
http://exampleclient.com and it opens
or i try with ip it opens.
then refresh the page it opens with www after 3-4 times.
i think it is because of a DNS issue. But i couldnt find where is the wrong config.
Me and all of my clients getting these errors. I wish i could fine the fix. thanks for your replies.
