429 status code error when minting token through Managed Guardian Service (MGS) on TestNet

[JoeyZhaojin]

Problem description

The error has appeared in the recent week. The completely same policy as previously, now VC and VP are generated, but no token is minted. Exporting and then importing and publishing a new policy also doesn't work.

As a reference, this is the policy message ID: 1715401522.501804003

Expected behavior

The policy can mint and allocate tokens as previously
