Every query fails, not only the one to do-host. They all fail within the same second. And the error is a Python NameError, not a timeout, an HTTP status or a TLS error. The tool never reached the network. Its HTTP client library, aiohttp, was not available to the interpreter it was running in, so each query died before it was sent. The do-host query merely happened to be the one whose failure is printed on screen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">python is a link to Python 3.6. Python 3.11 is installed next to it but is only used when called by its full name. A compiled .pyc file is tied to the interpreter version it was built for, which is why VxVerify ships in two builds: 3.x for Python 3.6 and 4.x for Python 3.11. Dell KB 000021527 documents the 4.x build with python3.11 for VxRail 8.0.x.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So the 3.x file did start under python, because the versions matched, and then failed inside because this appliance release no longer provides the modules it expects for Python 3.6.<\/p>\n\n\n\n<div style=\"height:34px\" aria-hidden=\"true\"
