Logs provide exact reason.

Look for lines containing error 2008, TLS, proxy, timeout, certificate.

When the UI is useless, the logs tell the truth. To extract deep debugging information:

Enable debug logging (temporary):

sentinelctl config debug-level 7
sentinelctl restart
# Reproduce the error, then:
sentinelctl logs zip

This generates a support_bundle.zip. Look for the curl_error string inside sentinelagent.log. Common 2008-associated codes:

The installer generates a detailed log. Navigate to:

%temp%\SentinelOne_Install_[timestamp].log

Search for the string "Error 2008". Look at the 5 lines before the error. You will often see a specific sub-error like: sentinelone error 2008

A common hidden cause: Windows Update has a pending reboot. The kernel is locked in a "pending" state, blocking new driver loads. Run:
