It continues this status for few days。Can you find some error info from the logs on your side with the url ？
Need I supply other information ？

Does it matter that my location is China？

[andypiper]

Location should have no issue as the fetcher just gets data from the site specified. You posted an image of a protected / private account, I’m not sure whether that is prioritised.

Thanks for your reply .

My side is still not well.
I think the fetcher post request from its server to my sites, so I dont know why it’s ok on your side but not ok on my side.
Does it matter with my location network or the dns of my domain(cri.cn)?
