An Access Gateway has the following issue when canceling changes to certificate modifications:
If you make certificate changes on the Reverse Proxy or the Web Servers page, click the link, and then cancel the changes on the Configuration page, the Reverse Proxy is configured with an invalid certificate.
To correct the problem, return to the page and select the old certificate. As soon as you exit the page, the certificate is pushed to the device. Because you did not change the certificate, you do not need to restart the Embedded Service Provider.
