see [High Performance Backend for Talk on Nextcloud with Docker](https://help.nextcloud.com/t/high-performance-backend-for-talk-on-nextcloud-with-docker/215828#p-648716-troubleshooting-10) and try creating a new `secretpasswordkey` **(min. 24 chars, better 32 chars**) **for each service**!

- replace `secretpasswordkey` in docker stack and restart the docker pulling the image.
- replace `secretpasswordkey` in your nextcloud Talk config
