You may get a "Connection Not Secure" or similar error trying to access the OTC Website. This can also occur on other websites.

This occurs if a security certificate expires and then is renewed, or gets modified/updated in some way. Some browsers (i.e. Firefox) cache certificates while others employ a practice called 'pinning'.  Your web browser may be caching the old security certificate with outdated information, which is causing this issue.

Method 1

Force Reload the page with its updated information: use the key combination Control+F5.

Method 2

Clear your cookies and cache.

If this does not resolve the issue, see if the problem occurs in another web browser, or on another network.
