iMessage cannot send messages

Hello everyone, I had recently posted about me being unable to log into imessage or facetime. I got a suggestion from a user to just wait for sometime. I followed his suggestion, waited for some day and Voila! I could log into imessage and call on facetime BUT I cannot send nor receive any messages. It appears as not delivered or the loading circle near the number stops and the number becomes red.

Some things I have already tried : 1) Used android tethering with horndis( Don't have actual ethernet)

2) Used wifi (realtek) with virtual bridge with ethernet (configured as builtin and en0)

3)Cleared Keychain, made new serials but kept my rom (mac of ethernet) the same.

Any help is appreciated.
