@sdetweil Thanks! I found the issue is that,

access to XMLHttpRequest at remoteServerAddress from origin ‘http://localhost:8080’ has been blocked by cors policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.

Trying to figure this now…

I have a compliments.json file on a remote server for the Compliments module loading that.
It worked in the beginning but after changing the language of MM2 from en to zh-cn, compliments cannot load the remote file then.
I have tried:

• reboot
• change back to en
• reinstall MM2
• update npm

but they all didn’t solve the issue.
I also found after that MM2 will be frozen (the clock is not running, the news feed won’t refresh), after launching MM2 for a while.
If put all compliments in the config without using remoteFile, everything works fine.

{
			module: "compliments",
			position: "lower_third",
			config: {
				compliments: {
					remoteFile: "http://remoteServerAddress/compliments.json"
				                          }
			             }
}

And my compliments.json:

{
    "anytime": ["Expelliarmus"]
}

Need some help, thanks!
