Cannot import reference from Pubmed

Hi, all.
Does anyone have trouble with peperpile button in PubMed now (16/Sep/20)?

The “paperpile” button is existing as usual, but I cannot download and import metadata into the paperpile when I click the button.
The error massage “Journal website is unresponsive.” was shown.
Reboot of Chrome and reinstallation of paperpile extension does not solve the problem.
Yesterday, the “paperpile” button worked well.

I could not break down this problem.
Issue of NCBI/Pubmed?, Paperpile?, Chrome?, or network problems of my institute?

Could you give me any suggestions to solve this problem?

I’m using MBP 2020, MacOS Catalina 10.15.6, and Chrome 85.0.4183.102.

Thank you

I have been having this problem this morning as well! I thought it was my network, but I’m guessing it’s something to do with NCBI/Pubmed.

The problem is gone away!
It seems to be a temporary problem.
