Error message

not support

What it means

check_ip returned a result but res.ok is False: the connection/handshake succeeded enough to return, but the response did not validate (host not supported on that IP).

Solutions

  1. Try a different SNI/host
  2. Use a known-good domain for probing
  3. Remove this IP from the usable pool
Defensive patterns

Strategy: fallback

Prevention

When it happens

Trigger: Script mode check where TLS connects but the expected domain response check fails.

Common situations: IP is CloudFlare but does not serve the requested host; wrong SNI.
