Can't get my gravatar to show up on my new self-hosted site

I switched over successfully from wordpress.com to www.remarpro.com (self-hosted), and found that my old gravatar doesn’t show up – it is something generic now. I went to Gravatar and changed my image – I wanted to update it anyway – but I still have the generic icon. I checked on Gravatar to be sure it has my email address, and also connected the same email to my www.remarpro.com account. Interestingly, my www.remarpro.com account now shows the NEW gravatar image, but it still doesn’t show up on my dashboard page.

Can you please help me make sure my new gravatar shows up on my website and on others when I comment? Thank you. FYI, My old image has a green background, and my new image has a white background.
