New error has entered the chat
Hello all, I've been using the obsidian/claudian set up for about a month now. I just received this error today. I'll begin clicking away at trying to resolve, but was curious if anyone has cracked the code yet? Thx "401 Invalid authentication credentials authentication_failed" - This almost always means Claude no longer has valid credentials to whatever service it's trying to use. It is not an Obsidian problem itself.

Solved: 401 Invalid authentication credentials (Obsidian + Claudian) I started getting API Error: 401 Invalid authentication credentials on every prompt, even something as simple as "I'm here". claude auth status showed I was already logged in, so it was a bit misleading. The fix was to open the Claude Code terminal and run: /login This refreshed the OAuth session. After seeing "Login successful", I restarted Obsidian and everything worked normally again. If claude auth status says you're logged in but Claudian still throws a 401, try /login before reinstalling or changing your configuration. It solved the issue for me.

am I late to the party?
Has anyone considered syncing calendars to obsidian/claudian/claude for recordkeeping and to make it easier to retrieve stuff? I'm open to advice, links, resources on the subject. Thx in advance.

Hey Crew,
I got carried away and reached the Claudian max limit for the next several hours. Anyone else hit this virtual wall yet? lol Thx for all the guidance @Kj Rainey
