Original GitHub issue: https://github.com/hibiken/asynqmon/issues/293

I run both docker and [asynqmon_v0.7.1_linux_amd64.tar.gz] file in CentOS Server, they all have some message like

Asynq Monitoring WebUI server is listening on port 8080
2023/02/20 12:25:48 http: superfluous response.WriteHeader call from github.com/hibiken/asynqmon.(*uiAssetsHandler).ServeHTTP (static.go:46)
2023/02/20 12:26:05 http: superfluous response.WriteHeader call from github.com/hibiken/asynqmon.(*uiAssetsHandler).ServeHTTP (static.go:46)
2023/02/20 12:26:06 http: superfluous response.WriteHeader call from github.com/hibiken/asynqmon.(*uiAssetsHandler).ServeHTTP (static.go:46)

and the web in browser have nothing show up.
The console had an error like:

Failed to load resource: net::ERR_INCOMPLETE_CHUNKED_ENCODING

Redis is working well, I tested the port is good.

Do you have any idea?

It is because your network speed is too low to load the webui js, well the Server blocked your request。
Look at the code ‘cmd/asynqmon/main.go’ at line 179 , change the timeout num
Then Build a docker image yourself
