I'm have the same issue with Home Assistant. I have tried setting SSL in Home Assistant but still has not corrected the issue.
"HTTPSConnectionPool(host='192.168.1.150', port=9091): Max retries exceeded with url: /zm/index.php (Caused by SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:841)'),))"
Any help on this would be great THANKS.
