The web service Netflow Analyser is down

Hi,

please help me solve the problem with the Netflow Analyzer web service.

Previously, access was carried out via tcp/8080 port. But today it was configured to use a tcp/https connection using a self-signed certificate. After these settings, the server was restarted and access was lost.
