Safari having problems accessing Apple support site!

Question

First it was one of the sites I need to access for my job (WebAdvisor). Then it began having problems browsing through pages of Ebay. Then it lost the ability to connect to MySpace. Now it is having problems connecting to THIS site, with error messages coming up for THIS board. All of the problems with Safari have happened in the last month.
WHY?

Answer 1

On this sit, there is (erratically) only a message that comes up on the page where this board appears, saying "An error has occurred."
On WebAdvisor, I get: "Safari can’t open the page “https://bcconline.bcc.edu/datatel/openweb/index.html” because it couldn’t establish a secure connection to the server “bcconline.bcc.edu”."
In MySpace, I get (only on Safari. It works on Firefox):
"Server Error in '/' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>"
On Ebay, it's erratic, so I can't copy the error message, but I think the error code number is -12229.
