Troubleshooting

Start with alexen doctor. It checks the container, certificate, database, nodes and license, and says what is wrong.

Problem	What to check
Cannot open the dashboard	alexen status; the address and port (https://domain:8000/dashboard/); the firewall.
Browser warns about the certificate	The panel uses a self-signed certificate (it was set up without a domain). Use a domain with a real certificate, or add the browser exception.
A node shows "Failed to connect"	The node server is off, the firewall blocks the node port, or the node's certificate is wrong. Re-run the SSH install from the node's row.
Users connect but nothing loads	Check the host's address, port and SNI against the inbound; check that the node's Xray is running.
An app says "device limit"	The user reached the device (HWID) limit. Remove a device from the user's edit dialog or raise the limit.
Users get 429 on their subscription	A rate limit in Subscription statistics → Limits or the Subscription settings was reached. Raise it or set it to 0.
You cannot log in after many tries	Your address was rate-limited or blocked. Wait 10 minutes, or unblock it from another admin's session (Blocked IPs).
The license shows "in use on another server"	Reinstalled or moved the panel. Ask the seller to move the license.
An update failed	The old version is put back automatically. Run alexen logs and send the last lines to support.
After restoring a backup something is missing	The backup is older than the missing data. Backups only hold what existed when they were made.
