Hi,
I have the latest NoMachine server in an Ubuntu 16.04 machine, and the latest client in macOS. Everything was working fine, until I had to change the password on the Mac and restart the computer. After restarting, I was asked to introduce the old password for the keychain access (as usual). But now I cannot connect to the NoMachine Server anymore.
The error is “Could not connect to the server. Error: Authentication failed”. I used to log in by password but this error shows up before I can introduce the username and password. I tried reinstalling everything in both sides and removing all the .ssh data but still the same.
The log is very similar to this post https://forums.nomachine.com/topic/starttcp-operation-not-permitted but no changes on the network were done.
Any suggestions are appreciated.
