12 months ago I had the same problem. I didn't figure out what exactly it was. On my machine in chrome and edge, the problem was repeated, but in firefox everything was fine. On another machine in chrome, everything was fine as well. In any case, the problem is on the browser side.
Description I am up docker docker-compose.yml file on my server, all conteaners successfully working on my mushin. When I using the control center and try the query to stream it was printed the following error message.
An unknown error has occurred. Check the connection settings.I want to mark that when I use ksqldb-cli and do the same query is working well.
Troubleshooting Not exists
