| Unable to establish a session |
Confirm the node, address, and local network are available; rule out corporate network-policy blocking. |
Retest on a known-good network without changing account and connection parameters at the same time. |
Node, time, source network, exact error text, and consecutive test results. |
| Display latency |
Lower resolution and color quality, and pause high-volume local uploads. |
Compare round-trip latency and jitter across networks to determine whether the issue persists. |
Node, resolution, network type, latency samples, and affected period. |
| Incorrect keyboard layout |
Check the local input method, session keyboard layout, and system region settings. |
Use a plain-text editor to test modifier keys, symbol keys, and shortcuts. |
Local system, keyboard layout, affected keys, and reproduction steps. |
| Clipboard not syncing |
Confirm that the session tool allows clipboard transfer, then test with short plain text. |
Reconnect the session and test again; do not start with large files or rich text. |
Session tool, content type, direction, and the smallest reproducible text. |
| Reconnect fails |
Fully exit the old session, wait for the connection to release, then retry with the original address. |
Check that the system account is still valid and avoid rapid repeated connection attempts. |
Disconnect reason, retry interval, exact error text, and most recent successful time. |
| Credentials no longer work |
Confirm that you are using the latest system username and session credentials, not an old record. |
Have an authorized owner verify the latest change and rotation time. |
Order number, node, username, and time of failure; do not attach the password. |
| Large-file transfer interrupted |
Use a verifiable, resumable file-sync workflow instead of relying on the clipboard. |
Compare source and destination file sizes and checksum results. |
File size, transfer direction, start time, failure stage, and checksum summary. |
