Ok, So that you reminded me that I need to test this from work, I too am seeing the same problem from work in accessing my 865L. Everything loads then after a long period of time I get the following:
"Unable to access your DIR-865L.
If you cannot access your DIR-865L, please check that:
You have at least 256K of bandwidth
Your DIR-865L is not being blocked by a firewall or an antivirus program"
My iPhone 4S is posting a error when connecting:
"Please check network setting and try again - (0.70.0.2.8.0)"
I see that the following is posted before logging into mydlink.com:
"Notice: Scheduled Maintenance
2013/04/30 00:00
In order to provide you with better service, the mydlink website will undergo scheduled maintenance on April 30 from 12:00AM to 4:00AM (UTC-7). The mydlink portal may be temporarily unavailable during this period. Should you require immediate assistance, please do not hesitate to contact D-Link Technical Support. We apologize for any inconvenience."
So this is supposed to happen tonight and I would recommend that we wait until tomorrow morning after 4am to see if anything has changed. If we can't get access by tomorrow, then it's time to phone contact level 2 or higher support.
