proxies:
- type: vless
  name: vl-reality
  server: xxx.xxx.xxx.xxx

The same configuration functions correctly on alternative frontend products, including Clash Verge Rev.

Have enabled the fields filter or something similar.
If you enabled it. You should also enable this field:

[love-2000]

Yes.

1. The Clash Fields filter is enabled on my device by default.
2. The global-client-fingerprint in Meta Fields Filter is disabled by default in a freshly installed version of Clash-Nyanpasu.
3. After applying a local configuration file (as shown in the previously shared sample config), the global-client-fingerprint in Meta Fields Filter is automatically enabled, as reflected in the Clash-Nyanpasu UI.

If you enabled it. You should also enable this field: global-client-fingerprint

But no, the Meta Fields Filter does not allow users to enable/disable the global-client-fingerprint field, as expected. The user interface indicates restricted behavior (cursor: not-allowed), preventing toggling of fields defined in the Clash configuration file.

After several testing, this issue only occurs in freshly installed instances of Clash-Nyanpasu with configuration files that define the global-client-fingerprint exclusively. The issue specifically affects users who have not interacted with the global-client-fingerprint field in the Meta Fields Filter. For users who previously clicked this field, the issue might not be able to be reproduced.

It appears that somewhere(maybe backend) value of global-client-fingerprint is not updated after the configuration file becomes active, despite the UI indicating that the field is enabled in the Meta Fields Filter.

Recording shows how to reproduce in freshly installed Clash-Nyanpasu.

@keiko233 I take the second glance at it, and I think it was a frontend issue?

[greenhat616]

Hi. I have commit a patch to solve this issue: 59a7e6a.
