## Expected behavior- I can add a valid redirect URI to an openId client by first adding it to the list of URIs and then affecting that change by hitting "Update" at the bottom of the openid client config page. ## Observed behavior- I can add the URI to the list, however when I hit Update, the page hangs on the spinning load indicator for about a minute, then disappears. My next page local load produces an Identity error page, and my change is not saved. I believe this change is related to our upgrade to 4.2.3 (from 4.2.1) but I'm not certain. We're going to be spinning up a 4.2.1 backup later today to see if we have any better luck with that- will update this post then.
