Web IDE Error, "An error occurred whilst loading all the files."

• Install gitlab in my server。

• Multiple domains(mydoname.com，mydoname.net, mydoname.cc） attach to the server BY DNS.

• Set external_url to "https://mydonam.com" in gitlab.rb

• Visit gitlab use "https://mydoname.com", Web IDE works

• Visit gitlab use "https://mydoname.net" or "https://mydoname.cc", Web IDE fails with message "An error occurred whilst loading all the files."

Multiple domains for same gitlab server, any other configuration items to pay attention to？

Thanks
