After update to Zabbix 5.0 custom script starts sent 503 error

[Gutsycat]

Zabbix 4.4 and script works fine.
After update to Zabbix 5.0 I receive 503 Server Error: Service Unavailable for url: http://<zabbix-ip-address>/zabbix/api_jsonrpc.php

I set request_terminate_timeout = 1d but this does not help.

Any help, please.

Did you install frontend from packages?

Can you please check does the frontend working? Looks like it is misconfiguration of web server.

Yes.

Frontend works but sometimes when I try to view Latest data I have the same 503 Error code.
Seems I need to configure some timeout variable but I do not know which one.

Zabbix requires to php.ini variable "max_execution_time" to be set not less as 5 minutes, if you receive 503 error in less time then you probably should configure your web server timeout. What web server do you use?
