Ubuntu 16.04.1 LTS
kopano-server is not able to communicate with kopano-search over https. This worked in earlier 8.2.x versions of Kopano.
Steps to Reproduce
Create a self-signed certificate like described in the Kopano Core Administrator Manual.
Configure kopano-search to bind on https port 1238, restart the service and check for port 1238 to open:
Test if a connection could be made:
Configure kopano-server to use the https port to connect to kopano-search and restart the service:
kopano-server is not able to connect to kopano-search and only reports the following log lines, even on log_level 6:
Communication between kopano-server and kopano-search is encrypted over https and working like in earlier 8.2.x versions of Kopano.
Troubleshooting/Testing Steps Attempted
Port binding on port 238 doesn’t work, it seems that it will only bind on high ports (above 1024). Binding to port 1238 via http works and kopano-server is able to connect.
As a workaround we could fall back to unix socket or http socket.
