Steps to reproduce

After more than a month of working without issues, I’ve recently encountered some problems.

It seems that the API-based Variable has stopped functioning as expected in the last few days. Unfortunately, I'm unable to pinpoint exactly when this issue started, though it might have occurred around the update to version 0.7 or shortly after.

I’ve verified that the endpoint is correct and accessible through Insomnia, where everything works as expected. However, according to the Cloudflare logs, it appears that Dify isn't even attempting to reach the endpoint.

The context of this bug is referenced here: #5717

I think this issue is due to this code https://github.com/langgenius/dify/blob/c5b3777d93dfbdfc0da338e1e93e909efa461548/api/core/agent/cot_agent_runner.py#L328-L338

I'm following up on this functionality. While it was working well in our latest code version, we've encountered a recurring timeout issue.

Details:

Previously Working: As @laipz8200 mentioned, the feature functioned correctly in recent days. Current Issue: Today, the feature stopped working again and resulted in a request timeout. Environment: We're using Hosted Dify (PRO subscription) on version 0.8.3 (signed as latest even if 0.9.1 is released on github).
