[Game Status (No Network Connection) Issue!!]

I am having this same issue

[FMO Help Thread]

I am unable to find any games when looking at the join online games tab, nor can my friends find any games that I host. I tried the fix listed in the OP with no success. I have whitelisted FM21 and Steam in my firewall, and have even tried running this with my firewall turned off but still have had the same issues. For reference, I had none of these issues playing FM20.

I submitted a support ticket to SEGA like the forum suggests, but the response to my support ticket directed me back here!
