Zabbix Scheduled Reports – Troubleshooting Connection to Web Service

I recently upgraded Zabbix to 5.4.1 and I wanted to start using scheduled report, but I've got some problems with conifguration (error Cannot connect to web service: couldn't connect to server).

My Zabbix is running in Docker on Debian Buster. Everything is based on official containers:
Zabbix Server (PostgreSQL), Zabbix Frontend (Apache, PostreSQL) and PostgreSQL12.

According do documentation (https://www.zabbix.com/documentation/current/manual/appendix/install/web_service) I installed Google Chrome browser:

• wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
• sudo apt install ./google-chrome-stable_current_amd64.deb

and Zabbix Web Service

• wget https://repo.zabbix.com/zabbix/5.4/debian/pool/main/z/zabbix-release/zabbix-release_5.4-1+debian10_all.deb
• dpkg -i zabbix-release_5.4-1+debian10_all.deb
• apt install zabbix-web-service

I eddited zabbix_web_service.conf:
AllowedIP=127.0.0.1,::1,0.0.0.0/0,zabbix

I edited zabbix_server.conf:
StartReportWriters=1
WebServiceURL=http://localhost:10053/report

I eddited settings in Zabbix Frontend – Administration -> General -> Other
Frontend URL: http://localhost:8085 (frontend is available at port 8085)

But when I try to test report generating i get error:
Cannot connect to web service: couldn't connect to server

I've already tried with other Frontend URLs, but nothings seems to work. I tried with:
http://localhost:10053/report
http://192.168.10.18:8085/
http://192.168.10.18:10053/report

I've verified that I get answear from http://192.168.10.18:10053/report :
{"detail":"Method is not supported."}

What else can I check/try?
