error when opening a document without error message in collabora.

Describe the bug I can't open documents in collabora. I didn't have a problem until now, but without identifying the changes it no longer works. I carried out the updates via portainer and docker compose and I realized that the coolwsd.xml file had changed. I reset the important settings then restarted the container. I can connect to the collabora server but I cannot open the files. and I have no errors in the collabora logs or in nextcloud. In the collaboration logs we see the start of the file opening and then a shutdown of the connection. I can't find why, thanks for any help you can give me.
