From the documentation, it says that pritunl-link supports Unifi UDM; however, it doesn’t say which version.

I see the below errors on the pritunl-link server. I’m currently running Unifi Network 7.3.76 with UniFi OS UDM SE 3.0.13. Could this be a version compatibility issue?

A Unifi update now changes the CSRF token after login. This is fixed in commit [**f92a8ce**](https://github.com/pritunl/pritunl-link/commit/f92a8cedbd25f214f7ba61215f7febef297eb971). This will be included in the next release. The source can be directly installed for testing with the commands below.

Do you know when this fix will be push to the ubuntu (focal) repo?

It’s available on the unstable repository. This can be used by editing the Pritunl repository file changing `stable` to `unstable` upgrading the `pritunl-link` package than switch the repository back to stable.
