google chrome bug?
It seems to be a problem with the Google Dictionary (by Google)
This script doesn't seem to exist or is not accessible by that port.
Based on some googling, this is a problem with a chrome extension, but it may not be clear which. (For me, it was Feedly).
The quickest way to find out which is causing the problem:
- Disable all your chrome extensions. (Chrome menu > tools > extensions)
- Refresh a page - hopefully the port error should be gone now
- Re-enable your extensions one by one, refreshing the page after each, 'til the error pops up again in the console. You should now have your culprit.
I know this could be a pain if there are a lot of extensions :/ personally, I took it as a chance to prune the unused / unworthy extensions while I was going through them.
