Can not access to web server

Submitted by Sabrina on 2015-03-29

Hi

Please I need your help.
I have long running WebIssues portal for few years. Since March 18, I reported a problem.
When trying to access the service showed an error indicating :

" Network Error (tcp_error)

A communication error occurred: "Operation timed out"
The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time. ".

For information, I have not generated any changes or updates at the server level. I do not understand what happened

Thanks, I hope you can help me.

Today the error displayed is:

"Your request could not be processed because an error occurred contacting the DNS server.
The DNS server may be temporarily unavailable, or there could be a network problem. "

someone can help me please ?
