Unable to connect to Collabora(Docker)

I want to use Collabora with NC on my intranet server (Ubuntu). We access the NC by IP address with a self certificate. And I want to use the Docker version of Collabora, but the certificate prevents me from connecting to the Docker version of CODE. I am unable to connect even if I ignore the certificate proof.

How can I get the Docker version of CODE to work?

[richdocuments] error: GuzzleHttp\Exception\RequestException: cURL error
60: SSL certificate problem: self-signed certificate in certificate
chain (see [curl.haxx.se/libcurl/c/libcurl-errors.html](https://curl.haxx.se/libcurl/c/libcurl-errors.html)) for
[127.0.0.1:9980/hosting/capabilities](https://127.0.0.1:9980/hosting/capabilities) at <>

I run update-ca-certificates to recognize my self-signed certificate. However, it is always a “cURL error 60: SSL certificate problem: self-signed certificate in certificate chain” error.

I do not have to use the Docker version. I may use the Nextcloud built-in Office. However, the built-in version always causes an ‘unable to connect error’ when each user connects for the first time.

What settings are needed to stop this connection error?
