Error code: PR_CONNECT_RESET_ERROR

I’m following the instructions to sync my phone with my computer, when I type firefox.com/pair as the instruction says I get the following error code see below. There doesn’t appear to be a way for me to contact mozilla as the error code says. The only fix is from 2018 and the discussion is closed. I tried to follow the 2018 instructions but that doesn’t work either. How to report this to mozilla as per the instructions?

An error occurred during a connection to accounts.firefox.com. PR_CONNECT_RESET_ERROR
