Something is going on in my droplet...
To start, I am sorry for such title that doesn’t give any information about the problem.
I was checking a site on one of my droplets and couldn’t login to wordpress and cvplab.
Then I logged in using Putty and updated the server.
Now I see memory usage is “95.1% of 29.40GB”;
I am trying to log in to CPVlab, it says: Could not open database connection
Should I migrate to a new server?
I see I am not the only one having this problem: https://www.digitalocean.com/community/questions/error-establishing-a-database-connection-wordpress
