I cannot login to Grist.
Okay, I am back in. That was weird. Not sure why it gave me that error message.
For anyone else encountering
"Failed to fetch" or
"NetworkError when attempting to fetch resource", this most likely means that the internet connection is down, or was down temporarily at an inopportune moment, so that when Grist attempted to talk to the server, it couldn’t.
The solution is to check your internet connection and reload the page.
Ha ha, good to know. Thank you for clarifying this, and thank you, Natalie, for emailing me back so quickly.
