Have got this error pop up only twice until now, but since I've never seen it before I want to know should I take this seriously or can I ignore it?

Has your server time changed recently?

That is typically the most common cause of that particular error.

It hasn't been changed recently (as per my knowledge) however I'll enquire with my host if they did something on their end.
