New bbb 2.3 installed on Ubuntu 18.04

Moodle 3.8.2+

bbb plugin: 2.1.15 (tried other version too)

The demo works.

I can get success message with curl from moodle server

No output for wget -qO- https://bigbluebutton.ezvclass.ir/bigbluebutton/api

Get error with wget -O -  https://bigbluebutton.ezvclass.ir/bigbluebutton/api from moodle server:

Resolving bigbluebutton.DOMAIN.TLD (bigbluebutton.DOMAIN.TLD)... xxx.xxx.xxx.xxx
Connecting to bigbluebutton..DOMAIN.TLD (bigbluebutton.DOMAIN.TLD)|xxx.xxx.xxx.xxx|:443... connected.
ERROR: cannot verify bigbluebutton..DOMAIN.TLD's certificate, issued by ‘/C=US/O=Let's Encrypt/CN=R3’:
  Unable to locally verify the issuer's authority.
To connect to bigbluebutton..DOMAIN.TLD insecurely, use `--no-check-certificate'.

The test server (default bbb setting in moodle) works fine.

The output of bbb-conf --check
