Sheduled report PDF blank or contains 404 page

[PrimalMinister]

I have set up the zabbix server and web service, both seem to be working fine. I am receiving the report in my email box with a PDF attached but the PDF is either blank or a 404 page. In my zabbix_server.conf I have the following:

WebServiceURL=http://localhost:10053/report

If I curl the service on the server I get:

curl http://localhost:10053/report

{"detail":"Method is not supported."}

So it looks like the service is running, the problem seems to be with the Frontend URL. I have set this to various settings including:

http://localhost
http://localhost:10050
http://localhost/report
http://localhost:10050/report
https://subdomain.domain.com # With my real domain
https://subdomain.domain.com:10050
https://subdomain.domain.com/report
https://subdomain.domain.com:10050/report

All I get is a blank PDF or one with a 404 page, this really has me stumped, I have literally searched all 86 results on google for 'front end URL zabbix' and various other terms, I can find nothing.

I hope someone can help, thanks.

Our resolution is:

1. Administration -> General -> Other: Fronend URL: https://Yours.DNS.adr

2.Zabbix server config: WebServiceURL=http://Yours.DNS.adr:10053/report

3.Web service config:
TLSAccept=unencrypted
IgnoreURLCertErrors=1

Its work for us :-) Not blank PDF

Worked for me as well. Actually not at first, but a reboot of the server may have helped.

I have in the meantime installed a preconfigured Zabbix Server Appliance 6.2.7 and installed web services, google chrome.
I have now root root access
I can generate and send reports but still getting the same empty pdf reports "with file not found"

What am I missing ? Any help appreciated

Configured the zabbix-server.conf
StartReportWriters=1
and
WebServiceURL=http://localhost:10053/report


Frontend URL http:/localhost/zabbix/ui

Configured zabbix-web-service.conf
AllowedIP=127.0.0.1,::1
TLSAccept=unencrypted
IgnoreURLCertErrors=1

no errors in the webservice log

Good news
I just managed to find a workaround that works. I was using Nginx in all my installations.

I swapped to Apache instead and it worked. It is possible that works with Nginx as well but not sure what exactly configuration is needed and where.
When switching to apache the front end server gui login changes from http://192.168.2.101/ to http://192.168.2.101/zabbix/

In case someone is still having issues and is using nginx. I found out that chrome is requesting the report on port 80 and since I was using nginx default install the default_server config was listening on port 80 which returned a 404. Removing the default server in /etc/nginx/sites-enabled, adding "listen 80;" to /etc/nginx/sites--available/zabbix and restarting zabbix-server solved it for me. It was also important to not mix http and https in the following config parameters

/etc/zabbix/zabbix-server.conf
StartReportWriters=1
WebServiceURL=http://localhost:10053/report

/etc/zabbix/zabbix-web-service.conf
AllowedIP=127.0.0.1
TLSAccept=unencrypted
IgnoreURLCertErrors=1

Administration->General->Other
Frontend URL http:/zabbix-server-ip

Reports->Scheduled Reports->Create Report
Owner -> Admin
Period -> Previous day
Cycle -> Daily
Start time -> 00:00
