Linux and its flavours are known for their many command-line utilities that simplify users’ jobs. However, since they don’t have graphical interfaces, any bugs or errors in these tools can be hard to diagnose as all you get is an error code on the terminal. 

In this article, we’re talking about Curl error 7, the reasons behind it and what you can do to fix the problem. 


What causes Curl error 7?

Curl error 7 can actually be triggered by a number of reasons including:

  • Background updates
  • The server isn’t responding or is down
  • Internet connectivity issues

How to fix Curl error 7?

Here are four fixes you can try out.

Check your internet

The first thing you should do in such situations is to check your internet connection. If you’re connected to a WiFi network, check if you have an active internet connection. Otherwise, you can try restarting your router or plugging in via LAN. 


Try again in some time

There’s a good chance that the receiving server is overloaded with requests and needs time to clear its pending overhead before it can get to new messages. Since the message is rather vague, you should wait some time and try again before trying anything else. 


Use HTTPS

If you’re using a program like curl or libcurl, entering URLs with the HTTPS prefix is necessary. Simply using the HTTP prefix means that the connection won’t be secure and will be dropped by the server more often than not, resulting in the error. Try replacing the HTTP:// with HTTPS://, and you should be ready. 


Check if your IP has been blocked

A lot of times, CURL might end up giving an error if the source IP you’re using to access the server is blocklisted. Especially if you’re trying to access the site over your school’s or office’s internet network, chances are they’ve blocked access to the particular server you’re trying to reach.

You can try a VPN to see if you can get around any such blocks. Using a VPN also gives you a new IP address, meaning you can circumvent any problems caused by your IP address getting accidentally blocklisted.
