You can try the option of --max-time.

Maximum time in seconds that you allow the whole operation to take. This is useful for preventing your batch jobs from hanging for hours due to slow networks or links going down. Since 7.32.0, this option accepts decimal values, but the actual timeout will decrease in accuracy as the specified timeout increases in decimal precision.

If you just want to check the http status code. You might want to check out the --head option.

I suggest using --silent with --show-error at the same time in case that you might want to know the error message.
