Zilliqa not mining?

[1971ECPT]

Hello everyone. I had observed zilliqa mining is not working since around 6 hours ago. 0 hashes on miner, rigel, or gminer, also pools are not found any blocks since 6 hours ago. Even wallet shows 0 coins.  Anyone knows what's happening? Thanks.

EDIT, this post can be deleted:

It was internal trouble, quoted from TW:


Hello everyone,

We are pleased to inform you that the network is now fully operational. In due course, we'll provide more information on the issue we encountered.

As always we appreciate your continued support during these challenging moments! 🙏

Regards,
