This “Checksum verification failed” error is really annoying. It basically means n8n downloaded the plugin file, but its “fingerprint” didn’t match what the official registry said it should be. It thinks the file is corrupted.
Since you are on n8n Cloud (where you can’t just open a terminal and clear the cache yourself), here is the best trick to bypass it.
Try this:
Go to Settings (bottom left) > Community Nodes.
Click the Install button.
Type the package name manually: n8n-nodes-browseract
Check the box and hit Install.
If my answer helped solve your question, would you mind marking it as the solution?
It’ll help others find it more easily—and I’d really appreciate it!
