Twitter API authentication error

I’ve been using the Twitter API connector almost daily for several months without issue, but today the Twitter Search and Twitter Timeline nodes immediately return this error:

Execute failed: Server returned HTTP response code: 401 for URL:

I have tried regenerating the access codes and even created a new API app, but to no avail. I’ve also restarted my computer and re-synced the clock. I also updated my Knime extensions, which I notice included updates in the Twitter and Google connectors category.

I can’t find any evidence that other people are suddenly running into this problem, but I thought I’d check in case it might be a Knime-specific issue (e.g. if Twitter has changed their API and Knime’s connector no longer works).

In any case, I’m out of ideas, and I really need this to keep working. So any help would be greatly appreciated.

Hi there @AngusVeitch,

seems another user experienced same and it ended up being issue on Twitter’s side.



Looks like you’re right - it was at Twitter’s end. I have since heard one other report of API issues occurring at that same time. And it’s all working for me again now. Cheers.
