I have multiple devices in two different countries (USA/Taiwan). They used to be table to talk to each other (via **8 xxx yyy zzz for example). Yet "recently" they are no longer able to reach other - there is now (404 not found error).
Truthfully I don't use this quite regularly such that I haven't actually know when it is broken.
I have tested that devices can reach reach other when they are on the same side of the Pacific, only those trying to cross the ocean that are blocked. All devices can reach **8 222 222 222 for loopback/echo service without problem.
Is this feature being removed?
