+# LBRY Exceptions
----:|---|---|---
+
-**1xx** | Initialization | **Daemon `start` and other CLI command failures (non-recoverable)**
+Exceptions in LBRY are defined and generated from the Markdown table below.
-**10x** | Client | Error codes reported by clients connecting to `lbrynet` daemon.
+
-101 | RPCConnection | Failed to establish HTTP connection to `lbrynet`. (Is it running?)
+Column | Meaning
-102 | RPCUnresponsive | HTTP connection established but daemon is not responding to commands.
+---|---
-103 | WebSocketConnection | WebSocket connection established but daemon is not responding to commands.
+Code | Codes are used only to define the hierarchy of exceptions and do not end up in the generated output, it is okay to re-number things as necessary to achieve the desired hierarchy.
-104 | WebSocketUnresponsive | Failed to establish WebSocket connection to `lbrynet`. (Is it running?)
+Log | Log numbers map to the Python Logging Levels and specify at what log level a particular exception should be logged. For example, a Log of "4" would be ERROR log level.
-**11x** | Hardware | Enough of `lbrynet` was able to start to determine external factors causing eventual failure.
+Name | Generated class name for the error with "Error" appended to the end.
-110 | OutOfSpace | Out of disk space.
+Message | User friendly error message explaining the error and possible solutions.
-111 | OutOfRAM | Out of RAM.
+
-**12x** | Environment | Internal factors preventing `lbrynet` from bootstrapping itself.
