wopi is the backend. So export COLLABORATION_APP_ADDR= should point to the onlyoffice frontend and COLLABORATION_WOPI_SRC= needs to point to the opencloud wopi backend service, which is a bit difficult to host without a proxy. Onlyoffice needs to connect to that service from the Web Client, that means you cannot use localhost or something like that.

Make sure that the wopi endpoint from the collaboration service is publicly available via https and has a valid TLS certificate.
