Have you tried toggling the remote access off (wait) then on at the settings? Also your router’s upnp actualy works? (the port opened by upnp e.g. 9080 and 9443 gets routed to your cloud ip) Check if you have other port forwardings that might overruled the upnp. Or better assign the ports manually on both router and cloud.
If those aren’t helping, I won’t explain this in details but this does help me sometimes after looking into the codes, try renaming your cloud at the settings.
