How can I change name of server which is running on-premise console? I changed it in “C:\Program Files\AVAST Software\Management Console\console\config\application-user-config.yml”, I restarted server, I downloaded new installer, but clients are still using old name.
I found, that on clients in file “C:\ProgramData\AVAST Software\Avast\var\bcc.cfg” there is still old name of server. Only solution that works is using avastclear.exe and reinstall Avast, but I cannot do this on all computers.
Mb… dns alias?
Nobody knows? I really cannot go to 200 PCs and manually uninstall and install again program. Reinstalling should fix this, but it does not. 
Following the instructions of the Clients Not Connecting To The Business Management (on-premise) Console section in the Avast Business Managed Troubleshooting Guide usually resolves this issue.
