Real Racing 3 progress issue

I got all the rewards for the current season, but for some reason
my overall progress is at 99% instead of 100%

I tried contacting firemonkies at the address: https://help.firemonkeys.com.au/, but got this in the browser:

An error occurred during a connection to help.firemonkeys.com.au. Cannot communicate securely with peer: no common encryption algorithm(s).

Error code: SSL_ERROR_NO_CYPHER_OVERLAP
