Warning
Couldn't verify username because servers are unavailable — Mojang login service down
Example error line
Couldn't verify username because servers are unavailable
Cause
The server could not verify a Minecraft account because the Mojang/Microsoft login services are temporarily not responding. This is not an issue with your server; players cannot join until the service recovers.
Fix
Wait for the external outage to pass. Do not turn off online-mode — that would open the server to fake accounts instead of solving the temporary problem.
