I found some relevant information regarding 403 errors in the Dify platform. A common cause of a 403 error when accessing image links is missing access permissions. The error message often indicates that the request is denied due to incorrect or missing authorization headers. The expected format for the Authorization header is Bearer <api-key> ^[1].

Additionally, there are similar discussions and issues related to 403 errors in the Dify repository:

1. I can't upload the image on dify workflow via api - This discussion is still open and might provide insights or solutions relevant to your issue.
2. 403 Forbidden - Another open discussion that could be related to your problem.
3. HTTP 请求时，提示403错误 - This issue is closed, and the suggested solution was related to another issue (#1542).

You might want to check these discussions for any updates or solutions that could help resolve the 403 error you're encountering with the multimodal large model in your self-hosted Dify instance.
