Sudden SQL problem - need to understand the source of the issue

So I have a list of servers as a website - out of no where - when you try to add a new server it gives an error - https://media.discordapp.net/attachments/346650145565179904/545234753142652932/unknown.png?width=1063&height=598 I went ahead and set a default value for it in phpymadmin, it asked for default values of more things - and after I set it it gave me some problems with the database. Any ideas what could be the source of this issue and where I could try to fix it?
