I know there have been several posts over the last few months on this (I replied to one yesterday but no response).
There was one earlier today about a potential issue with MCP Servers (I dont have any connected)
My issue is, sometimes when I am uploading an image in cursor I get the issue, if I leave it for sometime it seems to work again, but then when it does have an Anthropic Error, it can be stuck for an hour or so. However, text works fine (Just if I attach an image)
Its Claude-Sonnet
edit - Image isnt uploaded. this is the error - We’re having trouble connecting to Anthropic. This might be temporary - please try again in a moment.
