Sync login credentials are incorrect

[BG2VIA]

I'm trying to set up trilium server on Unraid and sync with desktop version. But I encountered a problem as below:

2022-12-06T14:48:31.552348039Z POST /api/login/sync returned 400 with response {"message":"Sync login credentials are incorrect. It looks like you're trying to sync two different initialized documents which is not possible."}
2022-12-06T14:48:31.552858199Z 400 POST /api/login/sync with 146 bytes took 1ms

It quite likes I need to add certification on desktop verions (windows), but I didn't find any docs about how to add certification on desktop version. Am I right on this guess? Anyone could guide me how to fix it? Thanks a lot in advance.

Best Regards
JJ
