Hi All, try turning off your ad blocker. I've had the same issue with "uBlock Origin" but if I turn it off for that page (login.ringcentral.com) then it works fine. (It does appear that this has slightly changed over the last few days though. It used to only be an issue with the two-factor security code.)

I realize that RingCentral doesn't want to support every possible browser extension out there, but ideally at minimum the error message should include something like "try turning off any ad-blocking browser extensions."

Having this issue 6/14/2022 and 6/15/2022 using Chrome. I tried this answer but I'm not running any Ad Blocker on Chrome. I disabled website advice extensions on Chrome. Nothing was able to get past this error message on Chrome. However, using Opera I was able to get past the message (without it showing) and reach the two-factor authentication screen (asks for code sent to phone). Hence I think the error message "service unavailable" may relate to the authentication service being unavailable. Still wondering why I can't get it done in Chrome.
