Zabbix 7.4.9 unable to get scheduled reports working.

[rbpowell]

I have an Ubuntu 24.04 running docker, my setup is a docker compose file with the following services PostgreSQL, Zabbix 7.4.9 Server, Nginx Web interface, Web Service, headless chrome, Agent 2, snmp Traps, Java Gateway, all running in same network subnet. I have added all of the variables for scheduled reporting. WebServiceURL, Allowed IP, Listening port, Frontend URL are all set, all testing shows everything working. When I run the test for the report I get this error:

2026/06/10 18:07:05.016034 received report request from 172.30.240.0:48568
2026/06/10 18:07:05.016498 making chrome headless request with parameters url: http://my.internal.com/zabbix.php?ac...shboardid=405& from=2026-06-09%2000%3A00%3A00&to=2026-06-10%2000%3A00%3A00, width: 1920, height: 1080 for report request from 172.30.240.0:48568

I can take the URL listed in the error and paste it into a browser and it opens the Dashboard in 2 secs. Guessing but the error sounds like something to do with chrome, but I have not been able to figure it out. Chrome is running and all tests shows it as working correctly and the configuration test all show good. I have even tried running chrome direct instead of a container on the server with the same error message.

Any help with this would be greatly appreciated.

Hi, were you able to fix it? I had the same error and solved it by changing the URL under Administration / General / Other... the Frontend URL needs to be accessible.

[rbpowell]

No, still having the same issue. The Frontend URL is accessible. Tried with just IP address and domain name, both worked during testing, but still get the same error.

I try long time ago this: (other problem but maybe inspiration for you)

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

[rbpowell]

Thanks for the reply. I tried with the TLSAccept=unencrypted under the Web Service, still same error. I already had all of the other settings including the IgnoreURLCertErrors.

Try it again on new deasboard -only with clock | CPU zabbix server. Try test simply deshboard
check al way from container routing/proxy/DNS mayby diferent look of wrontend
check that frontend fom container correct conect to ZBX srv.

life buoy - diferent version of component od bug in 7.4.9 (try on older or new version)

[rbpowell]

My test is just the Zabbix server dashboard. Everything I can find is showing working correctly, only issues is the actual error message when running the test itself. We had a previous version 7.4.5, it worked fine, may try and go back a couple of versions.
