Package: icinga2-bin Version: 2.10.3-2 Severity: important Hi
I upgraded the master and one satelite of a larger Icinga2 setup to Buster. After the upgrade those two instances where unable to establish a working API connection. Connections between the new master and the Stretch instances still works fine. API connections between two Icinga2 2.10.3-2 instances fail with timeout: | Jan 29 18:27:11 X icinga2[10213]: [2020-01-29 18:27:11 +0000] information/ApiListener: New client connection for identity 'Y' from [2001:db8::1]:53626 | Jan 29 18:27:21 X icinga2[10213]: [2020-01-29 18:27:21 +0000] warning/ApiListener: No data received on new API connection for identity 'Y'. Ensure that the remote endpoints are properly configured in a cluster setup. | Jan 29 18:27:21 X icinga2[10213]: Context: | Jan 29 18:27:21 X icinga2[10213]: (0) Handling new API client connection During this time the client should send an "icinga::Hello" message. Wireshark confirms that packets (in TLS 1.3) are flowing and arriving on the other side. But the Icinga2 core seems to be unable to receive them. The problem disappears if I start icinga2 by hand or with debug log level on the passive side of the API connection. With notice log level it get less frequent. I haven't tested anything newer yet.
