Big Contact- Cannot Send Email: Server Timed Out

I was just alerted that my contact form on my site throws this error:

Cannot Send Email: Server Timed Out

When someone tries to fill out the form. I just tested it and I do receive the email, but it still throws this error message. I have a feeling this has been going on for months as I’ve been getting multiple emails from the same people one after another (I think they just keep submitting the form and eventually give up.)

Anyway I’m not sure what might be going on or where I should start troubleshooting…
