Problem with storing credentials - API keys dissapear

I have a problem with N8N deployed from prebuild package on my qnap, and i have strong reasons to suspect its not qpkg related.

I have a fresh installation. I can create a workflow. i can create a credential. However, each time a pass an API key and save (with success notification), close the form, cretential is still in the Needs first first setup, and the API is empty.

No error messag. i couldnt find problem trace in n8n logs. Encryption key is set and couldnt change between api set and check. Browser window was not reloaded etc etc.

Any ideas where the problem could be ?

n8n Version 1.92.2

n8n stores credential data in a local JSON file. This file may be corrupted.

Some versions of n8n may not immediately reflect updated credentials due to browser caching.

Try pressing F5 to reload the page after adding the credential.

can you tell me where should i be looking for this JSON ? i found total of 5 credential.json none of which seems to be the one. more like definitions/dictionaries/configs.

refreshing browser doesnt help either.

watching wondering what this is too
