We are having a severe issue with one of our DNN sites and we haven't been able to resolve it. The site launched in September and has been working fine since then; then two weeks ago visitors started getting the "redirect loop" error when trying to access the home page. The issue was sporadic, happened across different browsers, and only when typing in “site.org” - not www.site.org, https://www.site.org, or https://site.org, or www.site.org/default.aspx. Restarting the application pools resolves the issue for about an hour. The frequency of the error occurring has lessened, but it is still happening a few times a day - generally during low traffic periods like 11-midnight and 6:30-7:30AM.  We've done some troubleshooting and have ruled out a DNS issue. The host conducted maintenance the day before the issue started happening but told us they were only making changes to the ControlPanel, not the server. Additional notes: The site is on 5.06.02 and utilizes an SSL certificate. We have all the pages checked in the page settings to be secure, and we are using a redirect setup in IIS to redirect from site.org to www.site.org. We were using the EasyDnnMobile redirect module to redirect mobile users to a mobile site, but after removing it, the error was still occurring so we don’t think that was the cause. 

Any ideas or suggestions anyone can provide would be much appreciated!
