ocket8888 opened a new issue #5103: URL: https://github.com/apache/trafficcontrol/issues/5103
## I'm submitting a ... - bug report ## Traffic Control components affected ... - Traffic Control Client (Python) ## Current behavior: When a connection-level error occurs, the scripts provided by the `toaccess` package crash, printing a stack trace to stderr. ## Expected behavior: When errors occur, scripts should print legibly what went wrong to stderr, then exit with an error code (it does exit properly with an exit code). ## Minimal reproduction of the problem with instructions: ```bash toget -fkp --to-url "http://notarealhost.test"; ping ``` ## Anything else: <details><summary>Stack trace</summary> ```Python traceback Traceback (most recent call last): File "/usr/lib/python3/dist-packages/urllib3/connection.py", line 156, in _new_conn conn = connection.create_connection( File
