Getting database connection error

I was writing a post and suddenly I am getting the database connection error. I don’t know what exactly happened.

Can anybody help me with this.?

I will ping the blog URL separately.

DM the URL.
I will check as according.
Usually it may be caused by database cache or object cache.
For troubleshooting, can you try onec by disabling the cache plugin installed in your website?

Thank you Rajdeep.

The issue has been resolved. I have restarted the server.

I don’t know what exactly happened because I hardly open the Wordpress dashboard. I was uploading one image and suddenly I got connection error.

Glad by hear :slightly_smiling_face:

FYI- I have checked with support the issue was happened due to insufficient RAM, almost 99% used by blog.
