Please explain here below what you were doing when the issue happened
Hi.
Browser cache sometimes causes problems when displaying widgets in embed maps.
In general, the browser cache behaves strangely in Carto.
Where in Cartodb to set a permanent token for map display?
It always helps to clear the browser cache.
Thank you very much.
Best regards,
Jan Jandourek.

Not a pro, just a humble user.
I think my problem can also be connected to that issue.
I use docker version (made by Sverhoeven) and run it on my improvised server. I remember having similar problem using regular carto server as well.
I am using carto for a year or so and have noticed that sometimes it has problems with retrieving data from server, as well it has an issue with loading tiles due to invalid token. It might be not working in Chrome if I had loaded that map previously, but may be working flawlessly in Firefox if I load it the first time, and vice versa.
"Invalid or nonexistent map configuration token"
It happens randomly with my maps and I don't quite understand why.
I couldn't also find any ways to reproduce it and to find any workarounds to fix the token. Cleaning browser cache doesn't actually seem to yield any results, token problem seems to stay anyway.
Not only it happens randomly, it also somehow randomly "fixes itself" after some time.

Can you share some workarounds on fixing that token issue?
