Can No Longer Connect To MailChimp API

For some reason my site can no longer connect to the MailChimp API. I had it set up for quite a while now and haven’t updated any plug ins in the last few weeks but it is giving me an error inside Enfold when I try to connect. Searching online it looks like a few people were maybe having an issue with the Google Maps API and MailChimp API inputs in the theme settings causing conflicts even though they are entered in different screens.

Has been like this for about 10 days, have cleared out all the codes, clear cache, re-entered and nothing is helping. Also switched back to my parent and de-activated other plugins but it didn’t help
