Is there a bug in HaaS?

Software SW bugs discussion

From May 18 I can see in the turris omnia syslog huge amount of records by HaaS. Repeating sequence (almost every minute):

But in HaaS.nic.cz report are reported only few attacks per day.
Is it an error/bug in HaaS software or misconfiguration? I’ll probably have to turn off HaaS.

May i suggest to add the haas proxy reload line to your ‘scheduled task’ in Luci > System > , it will solve these random hangups?

Thanks for the suggestion, but it does not help. haas-proxy is not relevant command. I don’t know how to restart haas service.

That is easy. Go to luci > system > startup en press haas proxy restart

Restart of haas-proxy doesn’t help either. I wanted to help with the research, but if I can’t, I’ll shut down Haas. Thanks.

It was already discussed here.

No, there is discussion about standard message “CRITICAL twisted 'channel open failed, direct-tcpip is not allowed” not about “CRITICAL twisted Unhandled Error”.
