Describe the Bug
It just randomly stopped working for anthropic models but does work for Chat GPT models. I’ve logged out, restarted, updated and it didn’t work. I created a new agent and it works for one message and then same issue happens.
“We’re having trouble connecting to the model provider” for anthropic models. Request ID: 80a8f389-dcb8-4362-ac57-5c148c338f4f
