Why does the message "We couldn't connect to Instagram. Make sure you are connected to the internet and try again" keep appearing after logging into INS? When logging into an Instagram account, even if the external network connection is normal, the login always prompts: We couldn't connect to Instagram. Make sure you are connected to the internet and try again.

The ultimate cause of this error message is: an external network issue.

Your external network node has been used too many times, causing Instagram to reject your access.

It is equivalent to your external network IP being added to Instagram's blacklist. As long as it is not removed, you will be prompted with a connection failure when logging in.

Simply change the network or switch to a new external network to continue logging in.
