• Using a web browser, attempt to access http://www.papilmob.ir/forum/robots.txt. If you are able to access it from your browser, then your site may be configured to deny access to googlebot. Check the configuration of your firewall and site to ensure that you are not denying access to googlebot.
• If your robots.txt is a static page, verify that your web service has proper permissions to access the file.
• If your robots.txt is dynamically generated, verify that the s that generate the robots.txt are properly configured and have permission to run. Check the logs for your website to see if your s are failing, and if so attempt to diagnose the cause of the failure.

• Using Webmaster Tools, find a day with a high error rate and examine the logs for your web server for that day. Look for errors accessing robots.txt in the logs for that day and fix the causes of those errors.
• The most likely explanation is that your site is overloaded. Contact your hosting provider and discuss reconfiguring your web server or adding more resources to your website.
• If your site redirects to another hostname, another possible explanation is that a URL on your site is redirecting to a hostname whose serving of its robots.txt file is exhibiting one or more of these issues.

After you think you\ve fixed the problem, use Fetch as Google to fetch http://www.papilmob.ir/forum/robots.txt to verify that Googlebot can properly access your site.
