What is your current rclone version (output from rclone version)?

rclone v1.72.1

• os/version: darwin 14.8.3 (64 bit)
• os/kernel: 23.6.0 (arm64)
• os/type: darwin
• os/arch: arm64 (ARMv8 compatible)
• go/version: go1.25.5
• go/linking: dynamic
• go/tags: none

What problem are you are trying to solve?

I would like to suggest the idea of automatic captcha passing. After a long mailru session, the agent issues a message asking you to complete the captcha. You have to stop the synchronization process, copy the url and paste it into the browser, and you don't have to solve any captcha manually. When you click on the link, the system immediately approves the passage. Can rclone do this by itself? It seems to me that this is a typical task - "error_code" is 13 for this.

How do you think rclone should be changed to solve that?

rclone could take the url from the "challenge_url" key and click on the specified link in the background. At the same time, you do not need to display a detailed message with the error body, but simply indicate "The captcha is in progress."
