You´re god! I was found upgrading schema (in /usr/share/icinga2-ido-mysql/schema/upgrade), here is 2.11.0.sql file… but how to upgrade it? Do you want to see content of this file? ---

Did you upgrade icingaweb2 as well? ---

It look´s icingaweb2 is on the newest version… ```auto root@vps-d03436bb:~# apt upgrade icingaweb2 Reading package lists... Done Building dependency tree Reading state information... Done icingaweb2 is already the newest version (2.8.1-1.stretch). Calculating upgrade... Done 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. ``` So… Yes, I did. ---

2.8.1 is the newest version. I’ve found [this](https://community.icinga.com/t/unable-to-detect-your-icinga-2-core-version/2749) issue, maybe you have a similar error? ---

I´ve found this issue too, but I have error php71 and on this issue is error php70… But thanks. I don´t really know, how to fix it ☹ BTW… what I must add to etc/hosts? Maybe this is the reason?

When you configure fqdn stead of ip addresses you need any kind of name resolution. One option is to put your fqdn into `/etc/hosts`. The last error indicates name resolution is not working or api port is not open. What is the result of `ping vps...` (please insert your fqdn). ---
