An error occurred while downloading a custom training model

[rainbow523]

When I use colab to train as usual today,
The program will encounter an error when downloading the custom model. I confirm that the download URL is valid.
The training model is the checkpoint I usually use. I also tried to upload the checkpoint to other websites that provide direct download links. Although the program will show that the download is complete, an error will still occur.
Has anyone encountered the same situation or knows how to deal with this problem?

My training parameters:
Image size: 896
Repeat:3
epoch:12
unet_lr : 5e-4
text_encoder_lr: 1e-4
network_dim:32
network_alpha:16
Keep other values ​​as default
