Hi, is your website under wordpress.com or ww.wp.xz.cn?? Because if your website is from wordpress.com meaning your website has “wordpress.com”, then you have come to the wrong support forums. This forums is only for ww.wp.xz.cn meaning, it is a full hositng site.
If you’re stuck in that connection loop, here’s what to do:
Do you have a caching plugin or service on your site? If so, you’ll need to clear the cache for your website. It may be a link at the top of your dashboard, or maybe in a plugin setting, or on the dashboard’s main page.
After the site’s cache is cleared, disable and then completely delete the Jetpack plugin on your Plugins page.
Then reinstall Jetpack, and attempt to connect again.
If you don’t have a caching feature, or you aren’t sure where to find it, we have a little alternative connection route plugin you can use.
Can you download this plugin:

Download the file, then install, and activate this plugin via Plugins > Add New > Upload in your site’s Dashboard (don’t expand the .zip file before uploading), then try to connect?
Once connected, please delete this plugin.
Let me know how it goes!
