Item net.tcp.service https vs http,,443

[JeffNL]

Ubuntu was updated from 20.04 to 22.04 on a ZabbixProxy. ZabbixServer is still at 20.04
Zabbix 6.4.5
Thereafter the https check did not function correctly anymore.

Does not function:
net.tcp.service[https]

Functions ok:
net.tcp.service[http,,443]

The result should be the same, but it isn’t.

I can solve this problem by changing the templates, but I am still curious as to how to solve the problem otherwise.
Does anybody know where I should take a look at?

as you see, they are not the same... one is httpS and other is plain http...

http

Creates a TCP connection without expecting and sending anything. Default port 80 is used if not specified.

https

Uses (and only works with) libcurl, does not verify the authenticity of the certificate, does not verify the host name in the SSL certificate, only fetches the response header (HEAD request). Default port 443 is used if not specified.

so if your https check does not work any more, maybe something wrong with libcurl ...
