Hi there, I am following up on an issue I'm seeing when trying to access Minecraft Server via the web as an admin, like this:

The error, across all browsers, but intermittently, is that the Login button click doesn't work. And sometimes the input fields do not appear at all. Yet sometimes the form works and I am able to access the in-game command line.
Web inspector shows the following errors:
Error: Internal Server Error
Request https://minecraft.cosmos.coop/js/superagent.js:74
emit https://minecraft.cosmos.coop/js/superagent.js:49
onreadystatechange https://minecraft.cosmos.coop/js/superagent.js:90
In the server logs for the app, I am seeing this:
Apr 17 15:23:53 ERROR ServiceUnavailableError: Response timeout
Apr 17 15:23:53 at IncomingMessage.<anonymous> (/app/code/node_modules/connect-timeout/index.js:84:8)

Apr 17 15:23:53 at processTimers (internal/timers.js:497:7) [ /app/code/node_modules/express/lib/application.js:630:43 ]
Can someone help me decode those errors? Thanks for your help!
