Smush Pro not recognising licence

For some reason the pro version of smush pro won't recognise it is installed despite having the dashboard and valid credentials loaded. The server environment doesn't seem to want to dial out.

I've activated support access so hopefully someone can figure it out and let me know. I have another site where this same behaviour happened but I could just use the standard version on that one despite the same scenario. For this site it is likely to be an ongoing issue so we need to have the pro version working.
