Collabora Connector Hangs, Crashes Firefox

Okay, I’ve mostly tried the collabora connector with compiled and installed loolwsd, loleaflet and LibreOffice following https://gist.github.com/m-jowett/0f28bff952737f210574fc3b2efaa01a, however I’ve also tried it with the docker version. Everything seems to be working, when I go to HOSTIP:9980 I see “okay”. Fine.

But when I try to access the test document specified by “https://localhost:9980/loleaflet/1.9.0/loleaflet.html?file_path=file:///opt/loolwsd/test/data/hello.odt” I get the “Service is unavailable. Please try again later and report to your administrator if the issue persists.” When I try to connect through the OwnCloud web, going to the ‘Office’ app runs a script that crashes asking to be killed after a few seconds the brings up the documents, but when attempting to edit one I get a 404 error. If I try to connect with NextCloud then it hangs forever.

I’ve had a look at my loolwsd log and three errors get repeated;

ERR FileServerRequestHandler: File not found: /opt//loleaflet/dist/branding.js
ERR Failed to write to pipe. Data: [spawn 1]. (errno: Bad file descriptor)| IoUtil.cpp:216
ERR ClientRequestHandler::handleClientRequest: WebSocketErrorMessageException: error: cmd=socket kind=serviceunavailable| LOOLWSD.cpp:1160

The first error with the double / seems pretty obvious, but I have no idea how to change it.

I’ve been troubleshooting this for a while now. Does anyone have any suggestions?

Yeah, using the Docker image I get the same result. When I click ‘stop script’ everything runs, but I cannot edit the documents. Clicking on them just opens up the download dialog for that file.
Trying to start a new file opens up a duplicate tab of the office app that then crashes firefox again.
