SSL Certificate errors when connecting to the Impinj R700 Reader

When the Impinj R700 are configured to use HTTPS as the default communication mechanism you may encounter SSL certificate errors when browsing to the reader's webpage or using the reader configuration REST API to make HTTP requests to the reader.  This occurs because the SSL certificate on the reader is self signed. Most browsers and HTTP libraries produce warnings when using encrypted HTTPS communication with a client that has a self signed certificate.  To continue you will to accept the certificate error to continue on to the webpage or for the HTTP request to complete.

Notice

In Impinj R700 Firmware version 7.4.0.240, the default mechanism for connecting to the reader was changed from HTTP to HTTPS. This change has been reverted in firmware version 7.4.1.240.

Below are some examples of web browser you may encounter, and how to proceed.
