Note, for people getting
error resolving "localhost:1234""/" ("") for "P.Q.R.S": rpc error: code = Unknown desc = no such record

Thats because of the VPN

I was having this issue with Firefox. Clearing out all the cookies/site data did not help. In the end restarting Firefox fixed the issue. The Pluto site was working, then it stopped working. Eventually I found the issues here and tries with Chrome and it worked, so I restarted Firefox and it started working :(

Hey there! Just checking to see if there is any general solution? I don't have a VPN and my only workaround for now is using Chromium

What is your problem? Can you make a video recording?

Weirdly, it doesn't happen anymore in the latest versions of Julia and Pluto. I will be sure to record it if it ever pops up again!
