As shown in the image, the email registration authentication service for InsForge was working fine previously, but for the past few days, it has been impossible to register new accounts because users are not receiving the verification codes. My server is deployed in Tokyo, Japan, and InsForge is in US-east. It is primarily targeted at users in mainland China. Everything was working fine before, but emails have not been arriving for the last few days. I hope the administrators can help resolve this. Thank you!
