Stealth redirects may not be supported by certain browsers or networks. This can cause errors with submission of forms because they required secure connections to the fully qualified domain name for the NetCommunity installation.
To resolve this issue, remove the stealth redirect from your domain with your DNS provider or internal redirect. For assistance in doing so, Please contact the appropriate software vendor or IT professional for assistance with this process or issue, which is beyond Blackbaud's scope of support.
