Troubleshooting
Start with the problem closest to yours. If these steps do not help, use Report a bug and tell us what you see.
The picture is blank or loading forever
Check your internet connection and refresh once. Try a different map. If only one map fails, mention which one in your report. In multiplayer, the timer keeps running while you refresh.
I cannot host a party
Sign in first. Hosting needs an account; joining a friend's invitation does not. Your host name comes from your account's Display Name.
My friend's invite will not work
Ask whether the party is full, already started, or closed. The host can create a fresh party if needed. Old unfinished parties expire after 24 hours.
My upload is taking a while
Open the map from My account and read its progress message. Preparing a large map can take time. If it shows an error, include that message in a bug report. Repeatedly uploading the same map usually will not help.
Upload button: clicked. Me, one second later: “Are we there yet?” ⏳

The classic waiting reaction. Check the progress message before trying the upload again. Meme source: Imgflip.
I cannot publish a friend's ZIP map
That is expected. You can play the imported copy privately and invite friends. Only the original owner can submit the original map for public review.
My contribution disappeared
Contributions leave the dashboard list after five days, but they are not deleted. Use the direct link if you kept it, or ask the map owner for help.
The capture says I am on the wrong server
Check that you joined the server the map owner told you to use. If it still fails, ask them to check the expected server address.
I cannot open an old guest bug report
Try the browser you originally used. Guest reports depend on that browser remembering you. For future reports, sign in or choose Keep this report in my account. Closed reports are deleted after three days.
The Windows app will not load
Check your connection, then try MineGeo in your browser. Tell support whether the website works and the app does not, or both fail.
Discord still shows a closed party
The message turns red and should disappear five minutes after the closed notice reaches Discord. If delivery is delayed, the invite's lobby page shows whether the party is actually open.
