Hello.

There are multiple reasons why an EC2 status check may fail, but the most common cause is a high CPU or memory load.
If you also check the EC2 system log, you may find that an error related to the cause is output.

Restarting EC2 may improve the issue, so please try restarting it.
There are other troubleshooting methods described in the following documents, so please try them.
