Cannot setup sync (v2)

### Describe your issue

I'm trying to setup sync with a local taskserver running on a rpi. The server works just fine (tested with 2 laptops), but if I go into the app settings and add certificates and taskrc file (a copy of the one I use on the laptop, without `taskd.certificate`, `taskd.key` and `taskd.ca`), I get all green ticks but at the bottom the popup says "Please setup your TaskServer"

### Steps to reproduce

1. Go to Menu
2. Profile -> Manage selected profile -> Configure Taskserver
3. Add `taskrc` (as explained above)
4. `Configure Server Certificate` set to `ca.cert.pem`
5. `Configure your certificate` set to `first_last.cert.pem`
6. `Configure your key` set to `first_last.key.pem`
7. Press the lightning (?) icon in the top right corner
8. All green ticks
9. Popup at the bottom of the screen says "Please setup your TaskServer"

### What was the expected result?

Taskserver correctly setup and sync enabled

Tái hiện vấn đề qua Menu > Profile > Manage selected profile > Configure Taskserver bằng các tệp taskrc và chứng chỉ được liệt kê. Truy tìm lý do cấu hình hiển thị các dấu kiểm màu xanh nhưng vẫn báo “Please setup your TaskServer”; hoàn tất khi taskserver được chấp nhận và tính năng đồng bộ hóa được bật.

Do mô hình lập chỉ mục viết ra từ nội dung của issue.
