What can cause a WebSocket connection to break in golang?

Question

go

What can break a WebSocket connection?
I have no more than 10 sockets connected at the same time on my local computer.
Started testing in different browsers. IE is generally thrown out every minute
In the code, I rewrote a lot and apparently messed up somewhere and now there are breaks.
In the error handler when the socket is disconnected, it says -not implemented
What is the reason for this and what can be done?

Answer 1

For starters - look for the source of the problem by the message.

fgrep -Rin 'not implemented' $GOPATH/src/ | grep -v '.git'
