X_Csize: 0 error when running sitemap generation

[erik4]

No problems for years and years, but suddenly this is cropping up everywhere I use the XML generator.

I tried adding IP info under Advanced settings but getting same result.

Additional info: sites are on shared cpanel server. Under advanced settings, I've tried both using the IP they're on (example 12.345.678.90) and also this way: 12.234.678.90/~accountname  ... but no difference, same error result:

There was an error while retrieving the URL specified: [ External links are visible to forum administrators only ]
HTTP Code:

HTTP headers:
x_csize: 0

Probably there is a configuration problem - it looks like your server doesn't allow local network connections via port 80 (http) or 443 (https) - as a result sitemap generator is not able to crawl the site. This is usually related to firewall installed at the host - could you please contact your hosting support regarding this?

Problem was corrected by restarting the WHM Cpanel CSF and LFD.
