My gif won't load. It outputs

Input image exceeds pixel limit. Width x height should be less than 71000000

But my picture is in line with the requirements.Why does this problem occur? Thank you. https://images.weserv.nl/?n=-1&url=https://pic.opop.vip/551f16624001291.gif

But the other one is normal.

The first image exceeds our pixel limit since it is 800x240600 (401 frames, with each frame being 800x600).

$ curl -LO https://pic.opop.vip/551f16624001291.gif
$ vipsheader 551f16624001291.gif

The second image does not exceed our pixel limit since it is 400x49500 (165 frames, with each frame being 400x300).

Well, it would be nice to be able to exceed the maximum number of pages for displaying gifs, after all, it would be uncomfortable if the images could not be displayed. Thank you very much for your answer!
