The KeenDNS connection problem started after updating the modem to version 5.0.4. There were intermittent disconnections and drops, and finally, the problem of not being able to access KeenDNS at all. Is this a new update or a different issue? When I click on KeenDNS via the mobile application, I get the same error: "This site cannot be reached. Please check if there are any errors in my writing."
