What @gsarvadnya said.: you’re using the latest version as of the time of this post.
If brave://help doesn’t connect when it checks for updates, but can use Brave to browse the web, I’m guessing it’s an issue created by antivirus program, like Kaspersky, which was flagging every Brave update until users complained about the false positive at which point Kaspersky would update the whitelist only to have the next update be flagged. If you’re running K or another similar application, I’d try updating that.
