Everything was working till yesterday. it starts failing today. I am using the google cloud build , so it takes the latest mux from repo. Local mux which is old is working fine.

I am using the compress handler like this

http.ListenAndServe(":8080", handlers.CompressHandler(r))

and serving static files.

but all the browser are not able to read the content. I tested with Mozzila , chrome and Microsoft EDGE.

Following error is shown

When I use without compress , things works but now my server slow without compression

http.ListenAndServe(":8080",r)
