https://golems.top/estimate issue

After upload the JSON file to https://golems.top/estimate, a batch process starts as expected, but after some minutes get stuck.
Now when the user log in the golems site, at least in my case nothing is reported in the estimation list.

This is part of the instructions:
9. After downloading JSON File, for manual way, upload it to https://golems.top/estimate with your credentials(you have to log in or register) to estimate your website. There is an available version to estimate your web resource without authorization.But in this case, the estimation result will be kept for a limited time. When automatic synchronization will be available, simply go to the service site https://golems.top. Log in, using access data that willbeavailable on "/admin/config/upgrade-check/result" page of your site. Estimation results will be available on resource https://golems.top on the profile page.
