"An error occurred while receiving the HTTP response to..." error message pops up almost immediately after the user tries to log into R80.10 SmartConsole.
Checking the Security Management side, no connection is attempted and there is no log in the cpm.elg and fwm.elg files.
tcpdump shows that no packet from the SmartConsole client is reaching the management server.
Netstat and Tcpdump outputs show an open connection to the Security Management Server on port 19009.
A tail on the Solr log (tail -F $FWDIR/log/solr.elg) does not show any activity or any lines added.
Cause
The Windows client was modified (or "hardened") to use only TLS 1.2, while SmartConsole and the Security Management server use TLS 1.0.
