When tried to run a test scheduled reports every time got 'Cannot connect to web service: couldn't connect to server' even if config was right and could see requests in tcpdump

After lot of debugging found out this:

ps -ef | grep zabbix_web_service
zabbix   2320615       1  0 23:04 ?        00:00:00 /usr/sbin/zabbix_web_service -c /etc/zabbix/zabbix_web_service.conf
root     2322048 2309912  0 23:12 pts/9    00:00:00 grep --color=auto zabbix_web_service
zabbix_web_service
zabbix_web_service [2322072]: ERROR: cannot open configuration file: open : no such file or directory

So SELinux has been disabled, server rebooted and after that it started to work. Based on Telegram community, web_service shouldn't even start if it can't read the config file. More detauails and logs are available in official Telegram account starting from 16.09.2024 22:09 CET
